Catalytic reaction and detection principle of glutamate dehydrogenase GLDH Glutamate dehydrogenase is a very important enzyme in the liver, involved in the metabolism of glutamate, α-ketoglutarate and other amino acids, so the detection of serum GDH content is an important indicator of health. The GDH enzyme preparation provided by Desheng is the raw material of the kit, which is mainly used for biochemical testing and related research experiments.

Application and storage of tris(hydroxymethyl)aminomethane TRIS Tris(hydroxymethyl)aminomethane is white crystal particles under normal conditions. The pH value of the acid-base indicator is 7-9. It has another name, tromethamine, ammonium tromethamine, THAM (English abbreviation), etc. Although they are all the same product, they are called differently in different application fields. Many people know that Tris has a very wide range of applications. Because it does not react with calcium, magnesium ions, and heavy metal ions, its performance is better than phosphate buffer in many aspects, so compared with Tris What are the common applications? What are the storage requirements?

Tips shared by carbomer 940 manufacturers Carbomer 940 is a polyacrylic acid polymer material with excellent thickening properties, gel properties and suspension properties. It has very successful applications in daily chemical products and pharmaceutical auxiliary materials. Carbomer raw materials produced by different manufacturers have certain differences. Here are some tips for using them.
Characteristics, application and storage recommendations of HEPES buffer HEPES (4-(2-hydroxyethyl)-1-piperazine ethanesulfonic acid) is a zwitterionic buffer with CAS number 7365-45-9. This buffer is usually used in biochemical experiments. To adjust the pH of the reaction system, this component is contained in virus preservation solutions or cell preservation solutions. It is non-toxic to cells and can control a constant pH range for a long time. It can not only be used as a buffer in the culture medium, but also as a pH regulator in cosmetics.
What are the common problems of accelerators and their causes? I believe that blood tests are indispensable when you go to the hospital for a physical examination, because many causes can be detected by blood. Serum is one of the main specimens tested in clinical biochemical and immunological tests. At present, the methods of obtaining serum samples in medical institutions are mainly obtained by centrifugation after collecting venous blood after the blood is completely coagulated. Under normal circumstances, it takes more than 60 minutes for an isolated blood sample to completely coagulate, or even not coagulate, which is difficult to meet the needs of rapid laboratory testing. The coagulant provides favorable conditions for shortening the coagulation process and quickly separating serum samples.
Two preparation methods of tris(hydroxymethylaminomethane) are big PK Tris in English and 2-Hydroxymethyl-2-nitro-1,3-propanediol in English. It is an important biochemical, chemical and pharmaceutical intermediate. Tris is the most common buffer component and titration standard in biochemical and molecular biology experiments. As a drug, it can effectively treat acidosis in patients with acute lung injury and induce phospholipid bilayer membranes to form monolayer membranes with corrugated structures. At the same time, it is also widely used as a solvent for nucleic acids and proteins, as well as many other important uses.
Components of blood coagulant Desheng Technology is a new technology enterprise specializing in the research and development, production and sales of blood collection tube additives. It has 15 years of experience in the production of blood collection tube additives. The main components of Desheng's blood coagulant are composed of thrombin, alcohol, silica powder, emulsifier, surfactant, etc., which are suspended liquids.
