Urea has been used to adjust the urea nitrogen concentration to a preferred range in blood reservoir for evaluating the dialyzer urea clearance to prepare standards to measure urea synthesis to prepare standards for blood urea nitrogen assay. 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.
