Buffer/ Excipient
ICH-Q7 GMP Manufactured ProductGUANIDINE HCl Buffer,
NF Grade, GMP Excipient Grade
Product Code: GHCL-3220 | Previously: GH3220
Intended For Critical Biopharma Applications
Guanidine Hydrochloride Buffer is a strong protein denaturant that functions as a chaotropic agent. As a denaturant, it acts to unfold proteins and turn them into their original polypeptide chains. As a chaotropic agent, it breaks down the structure of proteins. Guanidine Hydrochloride Buffer is commonly used in the purification of RNA by dissociating the RNA into its nucleic acids and protein forms. At higher concentrations, Guanidine Hydrochloride Buffer decreases enzyme activity. It is also used to increase the solubility of hydrophobic molecules.
