Chaotropic agent and strong denaturant; solubilizes cells.

Guanidine thiocyanate is a potent protein denaturant (stronger than guanidine HCl) often used in the isolation of intact ribonucleic acid to eliminate RNase
activity. RNase can recover activity after boiling, but is irreversibly inactivated in a 4 M solution of guanidine thiocyanate. Such solutions, to which the reducing agent b-mercaptoethanol is often added, are used to inactivate RNAse when isolating RNA from tissues that are rich in RNase, such as liver. Total nuclear and cytoplasmic RNA may be isolated this way. A protocol for extracting RNA with guanidine isothiocyanate has been published.
