Guanidine thiocyanate 99% supplier in China

Details:

1. Introduction of Guanidine thiocyanate

Guanidine thiocyanate , its cas register number is 593-84-0. It also can be called Guanidine, monothiocyanate ; Guanidinium thiocyanate ; Isothiocyanic acid, compd. with guanidine (1:1) (VAN). It is a white powder.
 

2. Basic Information of Guanidine thiocyanate

Guanidine Thiocyanate is an ultrapure, molecular biology grade reagent. It is free of detectable nuclease and protease activity and is a strong protein denaturant, as both the guanidinium cation and the thiocyanate anion are chaotropic agents. It is provided in one bottle containing 500 g. It is recommended for isolation of RNA, especially for tissues such as pancreas with high levels of RNase activity. In solution, it is known as guanidinium thiocyanate. Guanidine Thiocyanate is thoroughly tested for contaminating nonspecific endonuclease, exonuclease, and RNase activity.

4) uses

Guanidine thiocyanate (CAS NO.593-84-0) is mainly used in chemical reagent, biological medicine, etc.It is also used as a general protein denaturant, which is presumably the mechanism for its aforementioned application in humans. And it can be used to lyse cells and virus particles in RNA and DNA extractions, where its function, in addition to its lysing action is to prevent activity of RNase enzymes and DNase enzymes by denaturing them.
