General description

L-Cystine dihydrochloride is a vital component of biological systems, and its role in protein structure, redox chemistry, and cellular processes makes it a valuable tool in Biology and Chemistry research across a wide range of applications, from understanding fundamental biochemical mechanisms to drug development and nutritional research. L-Cystine is essential for studying protein structure and function. It can be used to create disulfide bonds in proteins, aiding in the formation of protein complexes and the stabilization of protein structures. This is particularly important in biotechnology and pharmaceutical research.

Application

L-cystine dihydrochloride has been used:

  • as a supplement to study homopropargylglycine update in metabolomics
  • as a supplement in protein synthesis for cell biology and stem cell research[1]
  • to study the effect of lipid peroxidation and ferroptosis by regulation of cysteine and GSH levels in biochemical research[2]

Biochem/physiol Actions

Cystine is the dimeric form of cysteine. Cysteine is the source of disulfide linkages in proteins and has a role in sulfur transport. It undergoes rapid oxidation to form cystine at physiological pH. L-Cystine is crucial for oxygen production and low density lipoprotein modification by arterial smooth muscle cells. It also has a role in the synthesis of glutathione.

Features and Benefits

  • High-quality compound suitable for multiple research applications
  • Suitable for mammalian cell culture
  • Prepared from non-animal source
  • Tested for Endotoxins

Questions

1–2 of 2 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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-mk.pdf

  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
