Description

General description: Urea is a colorless, odorless solid. It has prism-like crystals. It forms insoluble nitrate salts with nitric acid and oxalate salts with oxalic acid. On reaction with alkanes or substituted alkanes, it affords crystal-lattice inclusion compounds.[1]
Application: Used for the denaturation of proteins and as a mild solubilization agent for insoluble or denatured proteins. Useful for renaturing proteins from samples already denatured with 6 M guanidine chloride such as inclusion bodies. May be used with guanidine hydrochloride and dithiothreitrol (DTT) in the refolding of denatured proteins into their native or active form.
