Description

• Application: Guanidine hydrochloride solution has been used:for protein denaturationto homogenize hypothalamus, thalamus, prefrontal cortex, and brainstem samples for total β-amyloid (Aβ) extraction and Aβ42 quantificationas a chaotropic denaturant to treat human immunodeficiency virus-1 (HIV-1) samples to study its effects on HIV-1 sensitivity and to assay protein stability
• 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.[1] GnHCl can be used to extract proteins in extracellular matrix (ECM)‐rich tissues including bone, cartilage, ligament, and tendon.[2] Gnd-HCl is not used in proteomics experiments due to its interference with trypsin activity at low molar concentrations and tendency to precipitate when combined with sodium dodecyl sulfate (SDS).[1] It is appropriate for performing rapid and single-step affinity-purification mass spectrometry (AP-MS) experiments.
