General description

Urea is a chaotropic agent and is used for protein denaturation. It disturbs the hydrogen bonds in the secondary, tertiary and quaternary structure of proteins. Urea can also disturb hydrogen bonds present in DNA secondary structure.

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.
