| Message: | The chemical name of the biological buffer HEPES product is: 4-hydroxyethylpiperazine ethanesulfonic acid, a white crystalline powder. It is a weak acid and a zwitterionic buffer in organic chemicals. The decomposition ability of the substance can increase with the increase of temperature, and decrease with the decrease of temperature. However, compared with other buffers, its decomposition constant does not change much with temperature. This makes HEPES buffers more effective at low temperatures. A buffer to keep the structure and function of the enzyme well. It is widely used in many fields such as clinical laboratory diagnostic reagents, life science research, pharmacy and biotechnology.
1) The research of biological buffer HEPES on promoting the stability of foot-and-mouth disease antigen.
Foot-and-mouth disease antigen is easily degraded during storage and vaccine preparation, which affects the vaccine effect. The degradation rate of the foot-and-mouth disease antigen is related to the stability of the pH value of the maintenance solution. The preparation of a maintenance solution with strong pH stability can improve the quality of the foot-and-mouth disease vaccine.
2) Prepare a neuron-specific enolase content detection kit, which belongs to the field of human neuron-specific enolase content detection.
This detection kit has high sensitivity and a wide detection linear range, and has the advantages of simple operation, rapidity, strong specificity, good stability and high sensitivity.
In addition to HEPES, the biological buffers produced by Desheng include Tris, Bicine, Caps, Mops, Taps, EPPS, etc.; they are mainly used in biochemical diagnostic kits, DNA/RNA extraction kits and PCR diagnostic kits. Customers in need can provide samples. |
