Molecule Details
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 reagent1; Commonly used in conjunction with polyacrylamide gel electrophoresis for the fractionation of single-stranded nucleic acids with chains of up to 200 nucleotides2,3,4
