Guanidine hydrochloride

General description

Guanidine Hydrochloride is a potent protein denaturant extensively utilized in the purification of proteins and nucleic acids. Widely recognized for its versatility, it plays a pivotal role in total RNA extraction experiments, dissolving proteins and disrupting cell structures while inactivating RNA enzymes. Beyond denaturation, Guanidine Hydrochloride is instrumental in renaturing proteins, effectively restoring their active states. It also finds widespread applications in sequencing, molecular weight determinations, and acts as a solubilizing agent for electrophoresis. In summary, Guanidine Hydrochloride stands as a crucial tool in biochemical research, offering indispensable capabilities in the purification, denaturation, and renaturation of proteins and nucleic acids across diverse laboratory applications.

Application

Strong chaotropic agent useful for the denaturation and subsequent refolding of proteins. This strong denaturant can solubilize insoluble or denatured proteins such as inclusion bodies. This can be used as the first step in refolding proteins or enzymes into their active form. Urea and dithiothreitol (DTT) may also be necessary.

Guanidine hydrochloride (GdnHCl) has been used:

• to perform absolute quantitation of amyloid-beta (Aβ) isoforms in plasma
• in protein carbonylation assay
• for the quantification of glycosaminoglycans (GAG)
• for denaturation of cow‚Ä≤s milk allergens
• as a control in antiviral screening tests with coxsackievirus B3 (CVB3)
• in RNA isolation to dissociate nucleoproteins and inhibit RNase

Biochem/physiol Actions

Guanidine hydrochloride (GdnHCl) is hydroscopic and a small molecule. It is a potent denaturant of enzymes, which results in conformational changes in the enzyme, leading to complete loss of enzyme activity. GdnHCl is involved in blocking the activity of heat shock protein 104 (Hsp104) adenosine triphosphatase (ATPase) in vivo. It is involved in denaturing alkaline phosphatase (ALPase) in Haliotis diversicolor. GdnHCl leads to the deactivation of enzymes like papain and aminoacylase. GdnHCl, at higher concentrations, is effective in virus inactivation, such as herpes simplex virus 1 (HSV-1).
