Nucleic acid extraction refers to the process of separating nucleic acids from samples by physical and chemical methods. Isolation of high-quality nucleic acids is a key step in molecular biology research. Guanidine hydrochloride and guanidine thiocyanate can denature proteins and are widely used in......

This article details the principle of how Guanidine Hydrochloride denatures proteins.

If the denaturation conditions are severe and persistent, the denaturation of the protein is irreversible. Some denatured proteins can automatically return to their natural state after the denaturing factors are removed. This phenomenon is called protein renaturation.

The principle of new coronavirus nucleic acid detection is to expose the viral RNA through cell lysate, and then use real-time fluorescent RT-PCR for detection. Because the new coronavirus is very contagious, in order to protect testers and reduce the risk of infection, the virus needs to be inactiv......

Ammonium Sulfamate can absorb moisture in the air; it is insoluble in methanol and ethanol. It is hygroscopic. Decomposes by heat, releasing a large amount of inert gas.

Biological buffers are of great significance in biochemical research, and are widely used in experiments such as western blotting, biochips, and biological hybridization, as well as in vitro diagnostic industries. The biological buffer system contains 20-30 varieties, so what are the advantages of t......
