In enzymology, a dtmp kinase (ec 2.7.4.9) is an enzyme that catalyzes the chemical reaction: atp + dtmp rightleftharpoons adp + dtdp. Thus, the two substrates of this enzyme are atp and dtmp, whereas its two products are adp and dtdp. This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with a phosphate group as acceptor. This enzyme participates in pyrimidine metabolism.

Tyrosine is an important nutritionally essential amino acid that plays an important role in the metabolism, growth and development of humans and animals, and is widely used in food, feed, medicine and chemical industries. It is often used as a nutritional supplement for patients with phenylketonuria, and as a raw material for the preparation of pharmaceutical and chemical products such as polypeptide hormones, antibiotics, L-dopa, melanin, p-hydroxycinnamic acid, and p-hydroxystyrene. As more high-value-added L-tyrosine derivatives such as danshensu, resveratrol, and hydroxytyrosol are found in organisms, L-tyrosine is increasingly developing in the direction of platform compounds. Tyrosine is one of the 22 kinds of amino acids used by cells to synthesize proteins. It can be used to synthesize proteins in cells. Its codons are UAC and UAU. It is a non-essential amino acid that contains polar side groups and can be synthesized by the human body. The word "tyrosine" comes from the Greek tyros, meaning cheese. It was first discovered in the casein of cheese by the German chemist Justus von Liebig in the early 19th century. When it is used as a functional group or a side group, it is called tyrosyl. Function In addition to being a proteinogenic amino acid, tyrosine has a special role in signal transduction in proteins by means of a phenolic function, which functions as a receptor for phosphate groups transferred by protein kinases (so-called tyrosine kinase receptors). organ, while phosphorylation of hydroxyl groups alters the activity of the target protein. Tyrosine also plays an important role in photosynthesis. In chloroplasts (photosystem II), it is used as an electron donor in the reduction reaction of oxidized chlorophyll, allowing it to deprotonate the phenolic OH-group, and finally in Photosystem II is reduced by four core manganese clusters. Dietary Sources Tyrosine can be synthesized from phenylalanine in the body and can be found in many high-protein foods such as chicken, turkey, fish, milk, yogurt, cheese, cottage cheese, peanuts, almonds, pumpkin seeds, sesame, soybeans, lima beans , found in avocados and bananas.

Botanical Name - Momordica charantia Category - Medicinal Form - Dry Part Used - Fruit General Information - Momordica charantia (MC), a member of the Cucurbitaceae family, is also known as bitter melon, bitter gourd, balsam pear, pare, or karela. It is a widely grown and consumed vegetable in Asia, East Africa, India, and South America. The potential for MC to modulate blood glucose has received the most attention from investigators searching for natural foods or compounds that may be useful in the treatment of diabetes. Phytochemicals - The main constituents of bitter melon which are responsible for the antidiabetic effects are triterpene, proteid, steroid, alkaloid, inorganic, lipid, and phenolic compounds. Several glycosides have been isolated from the M. charantia stem and fruit and are grouped under the genera of cucurbitane-type triterpenoids. In particular, four triterpenoids have AMP-activated protein kinase activity which is a plausible hypoglycaemic mechanism of M. charantia.
The Chagas Ab Rapid Test is a lateral flow chromatographic immunoassay for the qualitative detection of IgG anti-Trypanosoma cruzi (T. cruzi) in human serum or plasma. It is intended to be used as a screening test and as an aid in the diagnosis of infection with T. cruzi. Any reactive specimen with the Chagas Ab Rapid Test must be confirmed with alternative testing method(s) and clinical findings. Chagas disease is an insect-borne, zoonotic infection by the protozoan T. cruzi, which causes a systemic infection of humans with acute manifestations and long term sequelae. It is estimated that 16-18 million individuals are infected worldwide, and roughly 50,000 people die each year from chronic Chagas disease (World Health Organization)1. Buffy coat examination and xenodiagnosis used to be the most commonly methods2,3 in the diagnosis of acute T. cruzi infection. However, both methods are either time consuming or lack of sensitivity. Recently, serological test becomes the mainstay in the diagnosis of Chagasâ??s disease. In particularly, recombinant antigen based tests eliminate false-positive reactions which are commonly seen in the native antigen tests4-5. The Chagas Ab Rapid Test is an instant antibody test which detects IgG antibodies the T. cruzi within 15 minutes without any instrument requirements. By utilizing T. cruzi specific recombinant antigen, the test is highly sensitive and specific.

Uncut Sheet Leishmania IgG/IgM Rapid Test Specimen:Whole Blood/ Serum/ Plasma INTENDED USE The Leishmania IgG/IgM Rapid Test is a lateral flow immunoassay for the qualitative detection of antibodies including IgG and IgM to the subspecies of the Leishmania donovani (L. donovani), the Visceral leishmaniasis causative protozoans in human serum or plasma. This test is intended to be used as a screening test and as an aid in the diagnosis of the disease of Visceral leishmaniasis. Any reactive specimen with the Leishmania IgG/IgM Rapid Test must be confirmed with alternative testing method(s). SUMMARY AND EXPLANATION OF THE TEST Visceral leishmaniasis, or Kala-azar, is a disseminated infection caused by several subspecies of the L. donovani. The disease is estimated by the World Health Organization (WHO) to affect approximately 12 million people in 88 countries1. It is transmitted to humans by bites of the Phlebotomus sandflies, which acquire infection from feeding on infected animals. Though it is a disease for poor countries, in Southern Europe, it has become the leading opportunistic infection in AIDS patients2-3. Identification of L. donovani organism from the blood, bone marrow, liver, lymph nodes or the spleen provides a definite means of diagnosis. However, these test methods are limited by the sampling method and the special instrument requirement. Serological detection of anti-L. donovani Ab is found to be an excellent marker for the infection of Visceral leishmaniasis. Tests used in clinic include: ELISA, fluorescent antibody and direct agglutination tests4-5. Recently, utilization of L. donovani specific protein in the test has improved the sensitivity and specificity dramatically6-7. The Leishmania IgG/IgM Rapid Test is a recombinant protein based serological test, which detects antibodies including IgG, IgM and IgA to the L. Donovani. This test provides a reliable result within 10 minutes without any instrumentation requirements.
The Cytomegalovirus Rapid Test is a rapid qualitative lateral flow test designed for the quantitive detection of Cytomegalovirus (CMV) in human serum/plasma samples. Cytomegalovirus is a herpes virus and a leading biological factor causing congenital abnormalities and complications among those who receive massive blood transfusions and immunosuppressive therapy. About half of the number of pregnant women who contract a primary infection, spread the disease to their fetus. When acquired in-utero, the infection may cause mental retardation, blindness, and/or deafness. Serological tests for detecting the presence of antibody to CMV can provide valuable information regarding the history of previous infection, diagnosis or active or recent infection, as well as in screening blood for transfusions in newborns and immuno-compromised recipients. The Cytomegalovirus Rapid Test Device (Serum/Plasma) has been designed to detect CMV through visual interpretation of color development in the internal strip. The membrane was immobilized with antigens of CMV on the test region. During the test, the specimen is allowed to react with colored recombinant mouse anti-human IgM latex conjugates, which were precoated on the sample pad of the test. The mixture then moves on the membrane by a capillary action, and interact with reagents on the membrane. If there were enough CMV antibodies in specimens, a colored band will from at the test region of the membrane. Presence of this colored band indicates a positive result, while its absence indicates a negative result. Appearance of a colored band at the control region serves as a procedural control. This indicates that proper volume of specimen has been added and membrane wicking has occurred.
Syphilis Test INTRODUCTION Anti-Syphilis Test is a rapid direct binding test for the visual detection of anti-syphilis antibodies in serum as an aid in the diagnosis of syphilis infection. Test results are read visually without any instrument. It is based on the principle of double antigen sandwich immunoassay for determination of syphilis antibodies in serum. Purified recombinant syphilis antigens are employed to identify anti-Syphilis antibodies specifically. This one step test is very sensitive and only takes about 10 to 20 minutes. Syphilis Test SPECIMEN COLLECTION For serum, collect blood into a container without anticoagulant. Allow the blood to clot and separate the serum from the clot. Use the serum for testing. If the specimen cannot be tested on the day of collection, store the serum specimen in a refrigerator or freezer. Bring the specimens to room temperature before testing. Do not freeze and thaw the specimen repeatedly. Syphilis Test PROCEDURE Strip 1.When you are ready to begin testing, open the sealed pouch by tearing along the notch. Remove the test from the pouch. 2. Immerse the strip into the container with the arrow end pointing towards the container. Do not immerse past the MAX (maximum) line. Take the strip out after 8-10 seconds and lay the strip flat on a clean, dry, onabsorbent surface (e.g., mouth of the serum container). 3.Wait 10-15 minutes and read result. Do not read results after 20 minutes. Cassette 1. Open a pouch containing a cassette, lay the cassette. 2. Using the plastic pipettor provided, draw about 2-3 drops (100mL) the sample into the sample well of the cassette. 3. Read results within 10-15 minutes. Do not read results after 20 minutes. INTERPRETATION OF RESULTS Negative: Only one pink band appears on test region of the Cassette. This indicates that there is no detectable Anti-Syphilis in the serum. Positive: Two pink bands appear on test region of the Cassette. This indicates that the specimen contains detectable amount of Anti-Syphilis. Invalid: If without colored band appears on test region, this is an indication of a possible error in performing the test. The test should be repeated using a new device. Syphilis Test PRECAUTION: 1. Must use fresh specimen and avoid repetitive freezing, the result will be invalid 2. Use it before expiry date. 3.The package of kit should not be opened until it reaches the room temperature if it taken out from the refrigerator. 4 .Old Serum can not be used. If the serum is thick, it can be used only after being separated. Syphilis Test LIMITATIONS The test is for in-vitro diagnostic use only.
Intended Use The One Step HAV IgG/IgM Test is a rapid chromatographic immunoassay for the qualitative detection of antibodies (IgG and IgM) to Hepatitis A Virus (HAV) in Whole Blood /Serum / Plasma to aid in the diagnosis of Hepatitis A Virus. Summary Hepatitis A is an acute, usually self-limiting disease of the liver caused by hepatitis A virus (HAV). HAV is transmitted from person to person, primarily by the faecal-oral route. The incidence of hepatitis A is closely related to socioeconomic development, and seroepidemiological studies show that prevalence of anti-HAV antibodies in the general population varies from 15% to close to 100% in different parts of the world. One step HAV IgG/IgM Test is a simple, visual qualitative test that detects Hepatitis A Virus antibodies in human Whole Blood /Serum / Plasma. The test is based on immunochromatography and can give a result within 15 minutes. Principle The One Step HAV IgG/IgM Test is a qualitative membrane strip based immunoassay for the detection of Hepatitis A Virus antibodies (IgG and IgM) in Whole Blood /Serum / Plasma. The test device consists of: 1) a burgundy colored conjugate pad containing HAV recombinant envelope antigens conjugated with Colloid gold (HAV conjugates) and rabbit IgG-gold conjugates,2) a nitrocellulose membrane strip containing two test bands (T1 and T2 bands) and a control band (C band). The T1 band is pre-coated with the antibody for the detection of IgM anti-HAV, T2 band is coated with antibody for the detection of IgG anti-HAV, and the C band is pre-coated with goat anti rabbit IgG. When an adequate volume of test specimen is dispensed into the sample well of the test cassette, the specimen migrates by capillary action across the cassette. IgG anti-HAV, if present in the specimen, will bind to the HAV conjugates. The immunocomplex is then captured by the reagent pre-coated on the T2 band, forming a burgundy colored T2 band, indicating a HAV IgG positive test result and suggesting a recent or repeat infection. IgM anti-HAV if present in the specimen will bind to the HAV conjugates. The immunocomplex is then captured by the reagent coated on the T1 band, forming a burgundy colored T1 band, indicating a HAV IgM positive test result and suggesting a fresh infection. Absence of any T bands (T1 and T2) suggests a negative result. The test contains an internal control (C band) which should exhibit a burgundy colored band of the immunocomplex of goat anti rabbit IgG/rabbit IgG-gold conjugate regardless of the color development on any of the T bands. Otherwise, the test result is invalid and the specimen must be retested with another device. Storage and Stability Store as packaged in the sealed pouch at room temperature or refrigerated (4-30 or 40-86). The test device is stable through the expiration date printed on the sealed pouch. The test must remain in the sealed pouch until use.
