The COVID-19 RT-PCR Detection Kit is a real-time RT-PCR test intended for the qualitative detection of nucleic acid from the SARS-CoV-2 in upper and lower respiratory specimens (such as anterior nasal swabs, mid-turbinate nasal swabs, nasopharyngeal swabs, oropharyngeal swabs, sputum, lower respiratory tract aspirates, bronchoalveolar lavage, and nasopharyngeal wash/aspirate or nasal aspirate) from individuals suspected of COVID-19 by their healthcare provider. Testing is limited to laboratories certified under the Clinical Laboratory Improvement Amendments (CLIA) of 1988, 42 U.S.C. 263a, to perform high complexity tests. Results are for the identification of SARS-CoV-2 RNA. The SARS-CoV-2 RNA is generally detectable in upper and lower respiratory specimens during the acute phase of infection. Positive results are indicative of the presence of SARS-CoV-2 RNA; clinical correlation with patient history and other diagnostic information is necessary to determine patient infective status. The agent detected may not be the definite cause of disease. Positive results do not rule out bacterial co-infection with other viruses. Laboratories within the United States and its territories are required to report all positive results to the appropriate public health authorities. Negative results do not preclude SARS-CoV-2 infection and should not be used as the sole basis for patient management decisions. Negative results must be combined with clinical observations, patient history, and epidemiological information. The COVID-19 RT-PCR Detection Kit is intended for use by qualified trained clinical laboratory personnel specifically instructed and trained in the techniques of real-time PCR and in vitro diagnostic procedures. The COVID-19 RT-PCR Detection Kit is only for use under the Food and Drug Administration's Emergency Use Authorization. PRINCIPLE OF DETECTION This product is a fluorescent probe-based Taqman RT-PCR assay system. Firstly, the RNA of SARS-CoV-2 will be reverse transcribed into cDNA by reverse transcriptase, and then PCR amplification will be performed with cDNA as template. During amplification of the template, the TaqMan probe will be degraded due to the 5'-3 polymerase activity and exonuclease activity of Taq DNA polymerase, then the separation of fluorescent reporter and quencher enables the fluorescent signal to be detected by instrument. The ORF1ab gene of SARS-CoV-2 will be detected qualitatively by FAM channel, the N gene of SARS-CoV-2 will be detected qualitatively by JOE channel, the E gene of SARS-CoV-2 will be detected qualitatively by ROX channel, and the internal reference will be detected by CY5 channel. dUTP and UNG enzyme are used in the kit to prevent contamination of the amplified products. Internal reference is used in the kit for quality control starting from sample collection

Acridine ester (NSP-DMAE-NHS), yellow powder, CAS number: 194357-64-7, is an important chemiluminescence reagent, its chemiluminescence quantum yield is higher than luminol, and it is labeled with acridine ester The conditions are mild, the labeling rate is high, and the separation is not affected after labeling. In addition, the chemiluminescence process of acridinium ester has a rapid reaction and low background, which can emit light in the presence of sodium hydroxide and hydrogen peroxide. During the oxidation reaction, the conjugate is decomposed and does not affect the luminescence of free acridine esters; in addition, acridine esters chemiluminescent reagents have good stability and are easy to store. In addition to its application in immunoassays, acridinium esters can also be used to label oligonucleotide fragment probes for genetic or microbial assays. Acridine ester compounds are very suitable for labeling DNA strands to produce chemiluminescent DNA probes. Modern medical research results show that many diseases such as cancer and genetic diseases are related to DNA mutations, and many infectious diseases are caused by viruses, bacteria or parasites in the environment. The analysis of virus specific sequence DNA is beneficial Control of the epidemic. The detection of DNA sequence and base mutation in its chain is of far-reaching significance in gene screening, early diagnosis and treatment of genetic diseases, and pathogenic gene determination. In nucleic acid hybridization analysis, the preparation of labeled probes with strong specificity and high sensitivity is the key to successful nucleic acid hybridization analysis. Acridinium ester derivatives can be directly labeled on nucleic acid probes without the need for catalysts and the luminescence quantum yield is not affected. In addition, under certain conditions, the labeled acridinium ester on the unhybridized single-stranded DNA is hydrolyzed and destroyed, and only the double-stranded protected acridinium ester formed by hybridization can produce chemiluminescence, and the entire hybridization process can be monitored without separation. Desheng Technology has been developing chemiluminescence reagents for 12 years. After successful development, it has been put into the market and has been widely recognized by customers. The acridinium esters developed and produced have 6 different groups of products. In addition to the acridinium esters, chemiluminescent reagents also include luminol and isoluminol. The luminous efficiency of the acridine ester series is relatively high and belongs to direct luminescence.
FOR COLLECTION AND TRANSPORT OF SAMPLESFOR NUCLEIC ACID AMPLIFICATION TESTS Intended use: VIROSWAB/TRANSFER is a transport system used for the collection and transport of cells from clinical samples or from the environment, for isolation of nucleic acids that will be used in nucleic acid amplification tests. Summary and explanation of the test: Amplification of nucleic acids isolated of the cells obtained from clinical samples or from the environment by methods like polymerase chain reaction (PCR) is widely used for various purposes like detection of infectious agents, identification of their genotypes, identification of DNA sequences that lead to genetic diseases, drug resistance, etc. The sensitivity of these methods is very much dependant on the appropriate collection and transport of the samples. VIROSWAP/TRANSFER is a kit prepared to enable this. VIROSWAP/TRANSFER is made up of two parts: Sterile dacron swab in a plastic package for collecting the sample and sterile transport medium in a crack-proof plastic tube. Samples obtained by the dacron swab is put in the transport medium. Specimens like a biopsy, scrapings, discharge can directly be put into the medium. Limitations: RNA molecules are very susceptible to nuclease digestion that may be coming from degrading cells. If amplification is intended to be done using RNA molecules as a template, it is recommended to transport the samples in an icebox and isolate nucleic acids within 4 hours. Principles of the procedure: VIROSWAB/TRANSFER is designed in a way to enable easy collection and appropriate transport of the samples. Polycarbonate tubes will not crack as glass tubes when the samples are frozen to preserve for an extended period of time. On the other hand the glass like transparent structure makes it easy to visualize and manipulate the samples. Dacron swab is kept dry; after collecting the sample the shaft of the swab is broken and the swab is placed into the tube containing the transport medium. The shaft of the swab is made from special plastic to enable easy breaking. The transport medium contains tris which keeps the pH around 8.0, which is suitable for nucleic acid preservation. Samples may contain nucleases (DNAse and RNAse) which will digest free nucleic acids and prevent their amplification. These enzymes require Mg++ as their co-factor to be functional. EDTA that is included in the transport medium strongly binds Mg++ and thus inhibits nucleases and preserve nucleic acids. Ingredients: Sterile dacron swab in a plastic package. Nucleic acid transport medium (20mM Tris (pH 8.0), 2mM EDTA) 3ml in plastic tube.

Luminol can be oxidized by many substances to produce chemiluminescence, which is the earliest research and most widely used luminescence reagent. The chemiluminescence analysis of metal ions occupies an important position in the entire research and application of chemiluminescence analysis. Some metal ions can enhance the chemiluminescence of the luminol system; some ions can inhibit the chemiluminescence of the luminol system; and some ions can directly oxidize the luminol to produce chemiluminescence. In our drug analysis, we use the catalysis or inhibition of metal ions and compounds for direct or indirect detection. Let's take a look at how luminol "extraordinarily" in drug analysis. Application of Luminol Luminescence System in Pharmaceutical Analysis 1. Direct or indirect detection using the catalysis or inhibition of metal ions and metal ion compounds, such as the determination of sodium nitroprusside (SNP) and catechol compounds. Certain reducing substances such as citric acid, citrate esters, Vc, ascorbic acid, etc. can also be detected by the metal ion-luminol luminescence system. 2. The enhancement or inhibition of the chemiluminescence reaction of luminol by biomolecules and organic substances. DNA, albumin, glucose, and uric acid can enhance the chemiluminescence reaction of luminol, thus establishing their own detection methods. In an alkaline medium, the inhibitory effect of ascorbic acid on the Luminol-K3Fe(CN)6 system can be used to determine ascorbic acid. Luminol-K3Fe(CN)6 series can also be used to monitor glucose and lactic acid. Thiol-containing drugs, promazine, etc. have an inhibitory effect on the luminol luminescence system, and a detection method is proposed accordingly. 3. Preparation of expendable chemiluminescence sensor. Luminol and other reagents are fixed on ion exchange resin to develop a chemiluminescence flow injection sensor, which is used for the determination of Vc. Combine enzyme immobilized column with FIA, use immobilized enzyme reactor, detect by luminol, it has been used for glucose, alcohol, oxalate, lactate, choline, uric acid in serum and urine, etc. Detection. Seeing more of the power of luminol, we suddenly discovered that it is acceptable to us wherever it is. This also fully illustrates its value. If you want to know more about luminol's knowledge and uses, you might as well find its manufacturer-Desheng. I believe you will be worthy of asking.

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.

Helicobacter pylori is a parasitic bacterium in the stomach that lives between the gastric mucosa and mucus. According to the WHO, more than half of the world's population has H. pylori and is the third leading cause of cancer-related deaths. In 1994, the WHO's IARC classified H. Pylori as a Class 1 carcinogen. The incidence of H. pylori in developing countries is the highest worldwide, highlighting the need for highly accurate and manageable testing. By 2025, the H. pylori testing market is expected to be worth 6 billion. Accordingly, SML Genetree has developed a reagent that can diagnose Helico-bacter pylori and Clarithromycin-resistant mutants (A2142G, A2143G) through DNA extracted from human hygienic tissue using Real-time Polymerase Chain Reaction. Since it contains multiple gene regions, Helico-bacter pylori and Clarithromycin-resistant mutations can be detected sensitively, and high reproducibility has been demonstrated through repeated tests by serially diluting various positive samples and standards. In addition, as a result of clinical evaluation on human sanitary inspection tissue by commissioning a large domestic consignment inspection institution, high sensitivity and specificity were confirmed, proving its excellent clinical performance.
