Guanidine hydrochloride
What is Guanidine hydrochloride?
Guanidine hydrochloride is a chemical compound with CAS number 50-01-1 and molecular formula NH2C(=NH)NH2 · HCl. It is used in various industrial and research applications.
Applications
Strong chaotropic agent useful for the denaturation and subsequent refolding of proteins. This strong denaturant can solubilize insoluble or denatured proteins such as inclusion bodies. 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.
