Description

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.
Other Notes: Denaturing reagent[1]; Commonly used in conjunction with polyacrylamide gel electrophoresis for the fractionation of single-stranded nucleic acids with chains of up to 200 nucleotides[2][3][4]
