Application

Guanidine thiocyanate has been used:
  • for the lysis of colorectal adenocarcinoma cell line prior to RNA isolation
  • as a PCR inhibitor in triplex mitochondrial DNA (mtDNA) qPCR assay
  • for DNA extraction from cerebrospinal fluid (CSF)

Chaotropic agent and strong denaturant; solubilizes cells.

Actions biochimiques/physiologiques

Guanidine thiocyanate is a denaturing agent and is used routinely in RNA isolation. It is used as a storage buffer for whole blood samples. Guanidine thiocyanate inactivates nucleases and is ideal for storing and freezing fecal samples for DNA studies. It is used in combination with phenol−chloroform in RNA extraction.
