Opis ogólny

Guanidine hydrochloride, also known as aminoformamidine hydrochloride, is a versatile compound widely used in molecular biology and biochemical research. Functioning as a potent chaotropic agent, it disrupts protein and nucleic acid structures, making it invaluable for purifying proteins, particularly mRNA. Its denaturing capabilities extend to unfolding proteins, aiding their purification and subsequent refolding, and it can even solubilize denatured insoluble proteins at higher concentrations.

At lower concentrations, guanidine hydrochloride exhibits a unique effect, promoting the refolding of denatured proteins and restoring enzymatic activity. This property is advantageous for protein renaturation studies. In RNA extraction, guanidine hydrochloride acts as a robust denaturant, disrupting cell structures and inactivating RNA enzymes, ensuring the integrity of extracted RNA. In summary, guanidine hydrochloride is a versatile compound with applications in protein purification, nucleic acid isolation, and protein refolding studies, showcasing its multifaceted utility in molecular biology and biochemical research.

Zastosowanie

Guanidine hydrochloride has been used:
  • as a component of the extraction buffer for the extraction of proteoglycans
  • in extraction during protein fractionation of ATDC5 cell lines
  • as a chemical additive to study its effective absorbance spectra in structural analysis
  • to incubate the device chip to release prostate-specific antigen and for regeneration of aptamer
  • as a component of the 2,4-dinitrophenylhydrazine (DNPH) solution for detecting protein carbonyls by protein carbonylation study
  • in RNA isolation to dissociate nucleoproteins and inhibit RNase
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.

Działania biochem./fizjol.

Guanidine hydrochloride (GuHCl) is a small hydroscopic molecule. It plays a role in inhibiting heat shock protein 104 (Hsp104) adenosine triphosphatase (ATPase) activity in vivo. It is a potent denaturant and inactivator of several enzymes and proteins. GuHCl can inactivate aminoacylase and papain. It is involved in unfolding and inactivation of alkaline phosphatase in Haliotis diversicolor. At higher concentrations, GuHCl is involved in virus inactivation such as Herpes simplex virus 1 (HSV-1).

Septin proteins evolved from ancestral GTPases and co-assemble into hetero-oligomers and cytoskeletal filaments. In Saccharomyces cerevisiae, five septins comprise two species of hetero-octamers, Cdc11/Shs1-Cdc12-Cdc3-Cdc10-Cdc10-Cdc3-Cdc12-Cdc11/Shs1. Slow GTPase activity by Cdc12 directs the choice of incorporation of Cdc11 vs Shs1, but many
