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. Shipping: 1.
