About

Guanidine Hydrochloride is hydrochloride salt of guanidine. Guanidinium chloride is a strong chaotrope and one of the strongest denaturants used in physiochemical studies of protein folding. At high concentrations of guanidinium chloride, proteins lose their ordered structure, and they tend to become randomly coiled, i.e. they do not contain any residual structure. Guanidine Hydrochloride is often used at high concentrations in both RNA and protein purification procedures. It denatures native proteins and thus inactivates RNases and proteases. This compound is frequently used in RNA purification, particularly for the isolation of intact mRNA from tissues or cultured cells. It is also extremely useful for dissolving protein inclusion bodies.
