The chromogen substrate TOOS is used to determine uric acid The chromogen substrate TOOS enzymatic spectrophotometric determination of uric acid is a commonly used method in the kit, in addition to the chromogen TOPS or TMB enzyme-linked immunoassay, the principle is similar. Desheng is a manufacturer of IVD raw materials, providing a variety of chromogen substrates such as TOOS, TOPS, and MAOS.
Advantages of chelating properties of biological buffer Bicine in papermaking coating N,N-Dihydroxyethylglycine has good chelating properties, and the coupling agent involved in the synthesis has a satisfactory effect on papermaking coating. After the coupling agent is added, the whiteness of the paper is not affected, and the napping speed and ink absorption are improved; at the same time, the viscosity is greatly reduced, and the rheology of the coating is enhanced, which is beneficial to the coating operation and reduces energy consumption.

Why do buffers contain surfactants In short, the buffer system can be modified with different surfactants to make the experiment easier to operate and more accurate. Desheng is a manufacturer of raw materials for biological buffers. Although it does not produce surfactants, some buffers such as Tris are also raw materials for the production of surfactants.

Advantages of acridine esters compared to other chemiluminescent substrates Acridinium ester chemiluminescence reagent is an advantageous reagent in tubular chemiluminescence. Compared with luminol, AMPPD, ruthenium terpyridine and other chemiluminescence substrates, it has unique advantages. It has ultra-high sensitivity and operation Simple and easy to automate operation.
Application of Chemiluminescence Reagents in Antigen and Antibody Detection With the development of testing technology, the detection of antigen and antibody is becoming more and more common. Whether it is health diagnosis, disease prevention or even new coronavirus detection, antigen and antibody detection can be passed. Chemiluminescence immunoassay is an important detection method. Luminescent reagents include acridinium ester, luminol and others.
Advantages of sodium fluoride-dipotassium EDTA combined anticoagulant in blood sugar Sodium fluoride-EDTA dipotassium combined anticoagulant is used to prepare blood glucose samples, which is more convenient to produce and has better anticoagulant effect. At the same time, it has the inhibitory effect of sodium fluoride on glycolysis and can effectively maintain blood sugar in the specimen. The relative stability of the concentration has great promotion and practical value
Tris can be used for green synthesis of gold nanoparticles the researchers used tris (Tris) as a reducing agent for the first time to reduce the chloroauric acid solution under alkaline conditions, by adjusting the ratio of Tris and NaOH, and the reaction time And adding stabilizers to control the synthesis of stable gold nanoparticles, the particle size is between 15-47nm.
