In Vitro Diagnostic Reagents Suppliers and Manufacturers

How much is 40 billion yuan? I believe that most people, like me, are a relatively abstract concept, simply a big number. Suppose you win 5 million prizes in the lottery, and you win 8,000 times. If it is used to buy in vitro diagnostic reagents, how much can you buy? How much serum separation gel can be bought for 40 billion? Usually the price of domestic serum separation gel is tens to one or two hundred per kilogram. We calculate at 100 yuan per kilogram, and 40 billion can buy 400 million kilograms of separation gel. Separating glue is generally 25 kg per barrel, and the barrel is about half a meter high. These barrels of separating glue can be connected to 8 million meters, which is a thousand times the height of Mount Everest and 800 times the depth of the Mariana Trench, the deepest part of the earth. How much can be done if these separating glues are added to the vacuum blood collection tube? Generally, coagulation tubes or anticoagulation tubes with a blood collection volume of 3-5mL add 0.8-1.2g of separation gel. We calculate by adding 1g separation gel per tube. These separation gels can be made into 400 billion blood collection tubes with a tube length of 10 cm. , Then these blood collection tubes can be connected from the earth to the moon back and forth 50 times, and can also go around the earth's equator 1,000 times, and weave a scarf for the earth. How much heparin can be bought for 40 billion? If you feel that the separation glue is not intuitive enough, then use 40 billion to buy heparin. The price of this is much higher. We calculate at a price of about 100 yuan per gram. The money can buy 400,000 kilograms of heparin. On average, 1300 pig small intestines can extract 1 kilogram of heparin. This heparin needs to sacrifice 520 million pigs, which is 4.3 of the total population of Japan. It is 1.6 times the total population of the United States and 70% of the entire European population! My goodness, if so many pig small intestines are used to extract heparin, the remaining pork is even more unimaginable. Of course, we canâ??t really spend 40 billion to buy separation gel or heparin. There are many in vitro diagnostic reagents that are more expensive than heparin, such as chemiluminescence reagent acridinium ester and enzyme preparations, antigen and antibody protein preparations, and the price is even higher than that of heparin. The milligram calculation is far more than that of gold, but usually the amount of these reagents is not much at one time, so the entire supporting products involved are also many. Desheng is a manufacturer engaged in the research and development of blood testing and virus testing related reagents, and welcomes the cooperation of in vitro diagnostic reagent companies.

The new Trinder's reagent is a highly water-soluble aniline derivative that has been widely used in diagnostic tests and biochemical tests. In the colorimetric determination of hydrogen peroxide activity, it has many advantages compared with conventional color reagents. The new Trinder's reagents are stable enough to be used in solutions and test line inspection systems. Currently chromogen substrates (new Trinder's reagents) include TOOS, TOPS, ADOS, ADPS, ALPS, DAOS, HDAOS, MADB, MAOS, etc. These new chromogens actually have similar reaction principles to traditional chromogens, but they have more advantages. We mainly understand the MAOS among them. The full name of MAOS is N-ethyl-N-(2-hydroxy-3-sulfopropyl)-3,5-dimethylaniline sodium salt. It is a highly water-soluble aniline derivative of the new Trinder's reagent. Which has a pivotal position. It is a water-soluble reagent that can be applied to the enzymatic photometric determination of hydrogen peroxide, and is widely used in diagnostic testing and biochemical tests. Reasons for the discoloration of the reagent solution: Color-developing substrates such as MAOS are all new Trinder's reagents, which are derivatives of highly water-soluble aniline sodium salt, which will produce red or yellow substances after being oxidized. Trinder's reagent powder is not easy to be oxidized. It needs to be sealed and refrigerated after preparation. If the solution is exposed to the air for a long time and the temperature is high, they may be slowly oxidized by the oxygen in the air. Discoloration of the solution occurred. MAOS is sensitive to light and sensitive to humidity. Therefore, when we store, the storage temperature of cold storage is between 0-10, and the temperature of frozen storage is below 0. If the storage temperature is not specified, in principle, it should be stored in a cool place below 15C. Hubei Xindesheng has focused on the research and development of a batch of new Trinder's reagents and other color reagents. The new reagent has more advantages: such as high water solubility, UV absorption of the color reaction product> 540nm; color reaction requires a wide pH range, and the activity of a variety of enzymes can be guaranteed during the reaction; color reaction sensitivity is higher and can be used For the determination of very small amounts of analytes. And it has considerable product advantages, purity: >99%, good water solubility, stable process, and can ensure the appearance of the product is pure white crystal powder. Welcome everyone to inquire.

Food safety issues have not only seriously affected the health of the people's diet, but also hindered the export trade of my country's agricultural products and food, and undermined the international reputation of my country's food industry. Only by strengthening basic food safety research, especially rapid testing research, can we adapt to the development under the new international situation. How to quickly and effectively do a good job of testing, we have to bring up our powerful chemiluminescence immunoassay to see through which aspects it plays a role in food safety testing. Detection of microorganisms in food The inspection of microorganisms in food is mainly to inspect general pollution and pathogenic bacteria. Escherichia coli O157 H7 is an important food pathogen. The enhanced luminol peroxidase luminescence system can quickly detect E. coli O157:H7. The method is simple and fast. The minimum detection concentration of each bacteria is in the range of 104105CFU/L, and the recovery rate is between 90% and 120%. Detection of biotoxins in food Biotoxin is a general term for a large class of biologically active substances, including animal toxins, plant toxins and microbial toxins. Biotoxins have posed a serious threat to food safety and human health. For example, the chemiluminescence enzyme immunoassay method for detecting aflatoxin M1 in milk uses horseradish peroxidase to catalyze luminol to emit light. Detection of pesticide residues in food Pesticide residues in food can cause chemical food poisoning, and low-concentration residues are also potentially harmful to the human body. At present, the most researched pesticide residue detection technologies are mainly in vivo detection methods, chemical detection methods, enzyme inhibition methods and instrumental analysis methods. modified products After recognizing the major changes brought to us by chemiluminescence reagents, Desheng has independently developed and produced chemiluminescence reagents since 10 years ago, including luminol, isoluminol, and acridinium ester and acridinium ester derivatives. product. These products are not only recognized by many companies in China, but are also well received even if they are exported overseas. Low-key life, high-profile work. What's more, a good product in the eyes of the public always speaks with strength.

Luminol has become one of the most widely used chemiluminescent reagents due to its advantages of high quantum yield, easy synthesis, and good water solubility. Its development process is the same as the arduous process of human beings. From the beginning, there is not much understanding, to the current glow and fever, it can only be summarized in one sentence: gold always shines. In the future, there may be more uses we don't know to benefit our lives. We only need to learn more about it to discover its unlimited potential as soon as possible. Application in the analysis of inorganic substances Using inorganic ions to enhance or inhibit the chemiluminescence of the luminol system, these metal ions can be measured. It is worth pointing out that some metal ions have higher catalytic activity than metal ions after being combined with complexing agents. For example, using the luminol-H2O2-silver phenanthroline system, the detection limit of silver ions can reach 2.7 10-g/L3. The use of sensitizers can improve the sensitivity of detection. The sensitization effect of triphenylmethane derivatives on the luminol luminescence system. It was found that Coomassie Brilliant Blue G250 had the best sensitization effect on the luminol-H2O2-Cu2+ system. A reverse flow injection technique was used to establish a measurement of Cu2+. The new method has a detection limit of 15. The use of the local concentration effect of surfactants to achieve micelle sensitization has been increasingly used in luminescence analysis. For example, the reversed micellar system FIA method is used to measure V4+, the detection limit is Luminol chemiluminescence analysis has been widely used in various fields, and new methods and new technologies are constantly emerging, especially the combination with FIA, HPLC and other technologies, which overcomes the shortcomings of poor selectivity in luminescence analysis and makes the analysis more flexible. Emblem and accuracy. Because of Rumi's stable performance and low price, practical application research and analysis will have broader application prospects.

How to use swab virus preservation solution 1. Before sampling, mark relevant sample information on the label of sampling tube. 2. According to different sampling requirements, use sampling swab to sample in corresponding parts. The specific sampling methods are as follows: a) Nasal swab: gently insert the swab head into the nasopalatine part of the nasal meatus, stay for a while, and then slowly rotate to exit. The other swab swabs the other nostril, immerses the swab head in the sampling solution, and discards the tail. (suitable for sampling with this product) b) Pharyngeal swab: wipe bilateral pharyngeal tonsils and posterior pharyngeal wall with swab. Similarly, immerse the swab head in the sampling solution and discard the tail. (suitable for sampling with this product) 3. Quickly put the swab into the sampling tube (including virus transport fluid). 4. Break the sampling swab at the broken place and tighten the tube cover. 5. Freshly collected clinical specimens should be transported to the laboratory within 96 hours at 4 - normal temperature, and those that cannot be transported to the laboratory within 96 hours should be stored at - 70 â?? or below. The samples should be extracted as soon as possible after being sent to the laboratory. The samples that can be extracted within 24 hours can be stored at 4. If not, they should be stored at - 70 or below

The new crown virus has broken the otherwise peaceful life and messed up people's lives. It is because of the extremely high risk of infection that everyone is afraid and cautious. When difficulties arise, methods to solve them will follow. In order to determine whether they are infected with the new crown virus, nucleic acid testing has made its debut. Nucleic acid testing is an important means to confirm the new coronavirus, and it is also one of the important processes for patients to confirm the diagnosis. To do nucleic acid testing, Nucleic acid detection has the characteristics of early diagnosis, high sensitivity and specificity, and is the "gold standard" for diagnosing new coronary pneumonia. Currently, the most widely used real-time fluorescent quantitative RT-PCR technology. Generally, the two targets located on the ORF1ab and N genes of the virus are detected. The same specimen must meet the double target positive or the repeated test as single target positive, or the two specimens must meet the single target at the same time to confirm the positive of SARS-CoV-2 virus nucleic acid. The virus transport medium developed by Desheng for the new coronavirus is inactivated and non-inactivated. The nucleic acid detection mainly uses an inactivated virus transport medium, which can instantly crack the pathogen and release the nucleic acid, and the protective agent can prevent the nucleic acid from being degraded. . By fully mixing the collected sample with the virus lysis solution and the virus nucleic acid preservation solution, the virus in the sample can be inactivated. Colleagues can effectively ensure the integrity of the virus nucleic acid in the sample. The collected sample can be transported and processed under normal temperature conditions. Long-term preservation. The saved viral RNA samples can be widely used in genetic testing, enzyme-linked immunoassay (ELISA), PCR testing, etc. Although Desheng does not currently have the technology to produce nucleic acid detection kits, it can produce virus preservation solutions, disposable virus sampling tubes and biological buffers required for nucleic acid detection, as well as luminol and acridine as the raw materials for antigen and antibody detection. ester. Desheng is willing to contribute its part in the fight against the epidemic, and is willing to fight for the cause of human health.

The chemical name of the biological buffer HEPES product is: 4-hydroxyethylpiperazine ethanesulfonic acid, a white crystalline powder. It is a weak acid and a zwitterionic buffer in organic chemicals. The decomposition ability of the substance can increase with the increase of temperature, and decrease with the decrease of temperature. However, compared with other buffers, its decomposition constant does not change much with temperature. This makes HEPES buffers more effective at low temperatures. A buffer to keep the structure and function of the enzyme well. It is widely used in many fields such as clinical laboratory diagnostic reagents, life science research, pharmacy and biotechnology. 1) The research of biological buffer HEPES on promoting the stability of foot-and-mouth disease antigen. Foot-and-mouth disease antigen is easily degraded during storage and vaccine preparation, which affects the vaccine effect. The degradation rate of the foot-and-mouth disease antigen is related to the stability of the pH value of the maintenance solution. The preparation of a maintenance solution with strong pH stability can improve the quality of the foot-and-mouth disease vaccine. 2) Preparation of a skin care product containing a biological buffer, which contains a microbial fermentation product extract, which is characterized in that it also contains a biological buffer with a mass percentage of 0.1%-3.0%. Advantages: The pH value of the product has a small drift range. Within three years after the preparation of the skin care product, the pH value can be stabilized at 6.0-8.0, which has a good protection for the microbial fermentation product extract added therein, and the microbial fermentation product extract is not Easily hydrolyzed, the anti-aging effect of the product lasts for a long time. 3) Prepare a neuron-specific enolase content detection kit, which belongs to the field of human neuron-specific enolase content detection. This detection kit has high sensitivity and a wide detection linear range, and has the advantages of simple operation, rapidity, strong specificity, good stability and high sensitivity. In addition to HEPES, the biological buffers produced by Desheng include Tris, Bicine, Caps, Mops, Taps, EPPS, etc.; they are mainly used in biochemical diagnostic kits, DNA/RNA extraction kits and PCR diagnostic kits. Customers in need can provide samples.

Since the outbreak of the epidemic, relevant diagnostic reagent R&D and production companies have introduced RT-PCR nucleic acid detection kits for the first time. By collecting oropharyngeal swab or nasopharyngeal swab samples, the RNA of the virus is extracted and purified for qualitative or quantitative detection. "2019 -New Coronavirus". The sample collection and storage container used in this method is a "disposable virus sampling tube". The new coronavirus nucleic acid detection, disposable virus sampling tube can be said to be indispensable. Next, Desheng intends to introduce the composition and use of the virus sampling tube. About the composition and manufacturing of the virus sampling tube: 1. Sampling swab: The sampling swab directly contacts the sampling site, and the material of the sampling head is closely related to the subsequent detection. 2. Virus preservation solution: There are two main types of virus preservation solution widely used in the market. One is the improved virus maintenance solution based on the delivery medium, and the other is the improved preservation solution of nucleic acid extraction lysis solution. 3. Preservation tube: The material of the preservation tube should be selected carefully. There are data indicating that Polypropylene is related to the adsorption of nucleic acids, especially when the ion concentration of high tension is high, polyethylene plastic (Polyethylene) is better than polypropylene (Polypropylene). Easy to grasp DNA/RNA. About the use of virus sampling tube: The virus sampling tube sampling is mainly divided into oropharyngeal sampling and nasopharyngeal sampling: 1. Oropharyngeal sampling: first press the tongue with a tongue depressor, and then put the sampling swab head into the throat to wipe the bilateral pharyngeal tonsils and back wall of the pharynx, wipe the back wall of the pharynx with light force, avoid touching the tongue unit. 2. Nasopharyngeal sampling: use a swab to measure the distance from the tip of the nose to the earlobe and mark it with your fingers. Insert the sampling swab into the nasal cavity in the direction perpendicular to the nose (face). The distance of the swab should be at least half the length of the earlobe to the tip of the nose. Leave the swab in the nose for 15-30 seconds, gently rotate it 3-5 times, and withdraw the swab. It is not difficult to see from the method of use that whether it is an oropharyngeal swab or a nasopharyngeal swab, sampling is a technical task, which is difficult and easy to contaminate. The quality of the collected sample is directly related to the subsequent testing. If the viral load of the collected sample is Low, easy to cause false negatives, difficult to diagnose.
