General description

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.

Application

Guanidine hydrochloride has been used:
  • as a component of the extraction buffer for the extraction of proteoglycans[1]
  • in extraction during protein fractionation of ATDC5 cell lines[2]
  • as a chemical additive to study its effective absorbance spectra in structural analysis[3]
  • to incubate the device chip to release prostate-specific antigen and for regeneration of aptamer[4]
  • as a component of the 2,4-dinitrophenylhydrazine (DNPH) solution for detecting protein carbonyls by protein carbonylation study[5]
  • 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.

Biochem/physiol Actions

Guanidine hydrochloride (GuHCl) is a small hydroscopic molecule.[6][7] It plays a role in inhibiting heat shock protein 104 (Hsp104) adenosine triphosphatase (ATPase) activity in vivo.[6] It is a potent denaturant and inactivator of several enzymes and proteins.[7][8] GuHCl can inactivate aminoacylase and papain.[8] It is involved in unfolding and inactivation of alkaline phosphatase in Haliotis diversicolor.[8] At higher concentrations, GuHCl is involved in virus inactivation such as Herpes simplex virus 1 (HSV-1).[9]

Features and Benefits

  • Highly versatile surfactant for your cell biology and biochemical research
  • Suitable for sensitive molecular biology applications
  • Free from Exonuclease, Dnase and Rnase
  • Tested to confirm low levels of heavy metal contamination, ensuring suitability for various applications

Preparation Note

In order to make an 8M solution in water, one must heat the solution to 35 °C for approximately 30 minutes.
The maximum solubility of guanidine hydrochloride in water at room temperature is approximately 6M.

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

    Amazing delivery!

    I'm shocked when I saw the guanidine bottle on my bench the very next day after I placed the order - impressive that they could deliver the reagent so quickly!
