- Description
- Guanidine Hydrochloride is a powerful, chaotropic agent which is widely used for purification of proteins and nucleic acids. Guanidine Hydrochloride is useful for denaturation and refolding of proteins as well as in the recovery of periplasmic proteins and isolation of RNA. At higher concentrations, this strong denaturant has been reported to solubilize denatured insoluble proteins such as inclusion bodies. When utilized at lower concentrations, Guanidine Hydrochloride is noted to be useful in prompting the refolding of denatured proteins. Guanidine Hydrochloride is also been reported to allow return of enzymatic activity in protocols using Guanidine Hydrochloride as a first step.
- Storage
- Store at room temperature. Hygroscopic.
- Usage
- To make an 8M solution in water, heat the solution to 35°C for approximately 30 minutes. The maximum solubility of guanidine hydrochloride in water at room temperature is approximately 6M.
Note: Guanidine HCl may clump during storage. It may
appear as a free-flowing crystalline powder, a free-flowing powder with solid material dispersed throughout, or a solid. The quality of the product does
not appear to be affected and solutions prepared from
the free-flowing and lumpy guanidine HCl appear
identical.
