The development layout of Desheng Biochemical in the field of in vitro diagnostic reagents

Release time:


At present, the development of the domestic biochemical industry can be described by leaps and bounds, and the stocks of biological companies and gene companies have also risen significantly. Desheng Biochemical, which started as a blood collection tube reagent, has also expanded rapidly in the field of in vitro diagnostic reagents. In addition to blood collection tube additives, it has gradually developed chemiluminescence reagents, color reagents, biological buffers, enzyme preparations and other products and Technology.

The diagnostic reagents are classified as follows:

1. Blood collection tube reagents

Contains blood anticoagulant sodium heparin, lithium heparin, dipotassium EDTA, sodium citrate, potassium oxalate, separating gel, coagulant, etc. For processing blood samples to obtain high-quality serum or plasma. Commonly used test items for blood collection tubes include routine blood test, four tests of coagulation, and white blood cell count. Among them, heparin and EDTA salts can also be used in many other biochemical research experiments or cosmetic and pharmaceutical raw materials.

virus preservation solution

This is a virus sampling tube additive, virus sample protection medium, used for the transportation and storage of nucleic acid detection samples. The sampling tube is similar to the blood collection tube, but instead of collecting blood samples, it collects samples for nucleic acid testing; the preservation solution includes inactivated preservation solution and non-inactivated preservation solution.


This is an organic polymer material used as a thickener, gelling agent, emulsifier, suspending agent and dispersing agent for daily chemical products or pharmaceutical excipients; it is commonly used in cosmetic creams, creams, lotions, shampoos, Shower gels, masks, and topical gels, etc. Carbomer has good water absorption, moisturizing, moisture absorption and waterproofing effects.

biological buffer

The more commonly used buffers are Tris (tris (trihydroxymethylaminomethane, tromethamine), whose performance is overall better than PBS, and is also used in coatings, new materials, and organic synthesis. Buffers can adjust the stability of the pH value of the system. In addition to Tris, there are Bicine, TAPS, MOPS, CAPS, HEPES and so on.

Chromogenic substrates, luminescent substrates

Substrates, as the name implies, are used with enzyme preparations. Such enzyme substrates are easy to observe and detect due to their color development and luminescence properties, and are often used as labeling reagents in detection to achieve the purpose of detection. Commonly used chromogenic substrates are TOOS, MAOS, etc.; luminescent substrates include luminol, acridine ester (without enzyme catalysis), etc.

Functionally, blood collection tube reagents are used in disposable vacuum blood collection tubes (containers) to collect blood samples to ensure high-quality blood or serum samples. This process belongs to the pretreatment of blood; and the subsequent buffering Reagents, chromogenic substrates, and luminescent reagents are used in the mid-processing or post-processing of blood (or other body fluids) to detect biochemical items other than coagulation function and blood routine, such as blood sugar, blood lipids, liver, kidney function, etc.
