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.
