Application

Urea is typically used for the denaturation of proteins and as a mild solubilization agent for insoluble or denatured proteins. It is useful for renaturing proteins from samples already denatured with 6 M guanidine chloride such as inclusion bodies. Urea may be used with guanidine hydrochloride and dithiothreitrol (DTT) in the refolding of denatured proteins into their native or active form.
