Guanidinium hydrochloride

Guanidine Hydrochloride is a strong chaotropic agent useful for the denaturation and subsequent refolding of proteins.


This strong denaturant can solubilise insoluble or denatured proteins such as inclusion bodies and be used for the recovery of periplasmic proteins. This can be used as the first step in refolding proteins or enzymes into their active form. Urea and dithiothreitol (DTT) may also be necessary. It is also used in the isolation of RNA to dissociate the nucleoprotein into its nucleic acid and protein moieties. It is an inhibitor of RNase.
