Application

Guanidine hydrochloride solution has been used as a fixation buffer in genomic DNA extraction for genomic analysis.

Biochem/physiol Actions

Guanidine‐HCl (Gnd-HCl), an efficient chaotropic agent, is broadly used in RNA isolation, globular protein denaturation, and protein refolding studies as a denaturant. It is an appropriate sample buffer for the quick and effective elution of affinity-purified protein complexes and the subsequent protein digestion step. Gnd-HCl is not preferred in proteomics experiments due to its hindrance with trypsin activity at low molar concentrations and tendency to precipitate when combined with sodium dodecyl sulfate (SDS). GnHCl is commonly utilized to extract proteins in extracellular matrix (ECM)‐rich tissues including bone, cartilage, ligament, and tendon.

Protein digestion is an integral part of the "shotgun" proteomics approach and commonly requires overnight incubation prior to mass spectrometry analysis. Quadruplicate "shotgun" proteomic analysis of whole yeast lysate demonstrated that Guanidine-Hydrochloride (Gnd-HCl) protein digestion can be optimally completed within
