Application

Guanidine hydrochloride is commonly used as a denaturant, because of its ability to break hydrogen bonds between amino acid residues. By breaking these bonds, the 3D conformation of the protein is unfolded and the aqueous solubility of the protein is greatly increased. Once denatured, the protein can be easily reduced, modified, or analyzed, in a variety of procedures. Further processing of the sample can allow the proteins to be analyzed by other common protein analysis methods including mass spectrometry, electrophoresis, and enzymatic digests.
Guanidine hydrochloride has also typically been used for the isolation of RNA, to denature globular proteins, and for protein refolding studies. It can also be used to facilitate the generation of tryptic peptides for analysis of complex protein samples.

Physical form

This product is a ready-to-use 6 M guanidine hydrochloride solution. The 6 M Guanidine hydrochloride solution may be used as a stock solution to prepare solutions of lower concentrations as appropriate.

Note: If precipitation is present in the 6 M buffer, warm the bottle to 37 °C and mix until completely dissolved prior to use.

Questions

1–4 of 4 Questions  
  1. 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.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  3. Is the aqueous solution of guanidine HCl considered a buffer, or is it prepared as an aqueous solution and not in a buffer?

    1 answer
    1. Guanidine is a strong organic base, making SRE0066 an aqueous solution. In technical terms, guanidine has a pKa of 13.6, indicating that it is a strong basic buffer.
