General description

Hyaluronic acid (HA), a vital component of the extracellular matrix in the central nervous system, is the versatile macromolecule found in the connective tissues of all vertebrates. This supramolecular glycosaminoglycan is a polyanionic natural polymer occurring as a linear polysaccharide. It is made up of glucuronic acid and N-acetylglucosamine repeats through a β-1,4 linkage. HA is seen abundantly in the eyes, joints, and heart valves.

Application

Hyaluronic acid sodium salt from Streptococcus equi has been used:
  • with methacrylic anhydride for synthesizing cross-linkable methacrylated HA hydrogel (Coll-MeHA)
  • in phosphate buffer saline (PBS) to replace the PBS bath to vary the lubricant composition
  • in the preparation of lubricant to study its effects on the boundary lubrication of human osteoarthritis (OA) cartilage

Biochem/physiol Actions

Hyaluronic acid (HA), an important component of synovial fluid and articular cartilage serves as the boundary lubricant. It exhibits several physicochemical properties including biodegradability, biocompatibility, nontoxicity, and nonimmunogenicity. HA is considered a great tool for biomedical uses like drug delivery, tissue engineering, plastic surgery, ocular surgery, and osteoarthritis surgery. It participates in cushioning and lubricating the body. This powerful antioxidant can bond water to tissue.

      Helpful?

  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.
      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

  4. May I know the formula and MW for one unit of Hyaluronic acid? And I also need the formula and MW for one unit of Hyaluronic acid Sodium. Thanks!

    1 answer
    1. The linear formula for hyaluronic acid sodium salt is [C14H22NNaO11]n where n is the number of monomeric units present in the polymer. This would equate to 403.31 g/mol for each unit. Hyaluronic acid has the linear formula [C16H27NO11]n which would have a molecular weight of 409.39 per unit.

  5. 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

  6. Is this suitable for sterile use or should it be sterilized and how would you recommend to sterilize?

    1 answer
    1. TS Answer: This product is not sterile, however, prepared stock solutions may be autoclaved or filter-sterilized. The estimated molecular weight range is 0.85 to 1.6 million daltons. Filtration studies of high molecular weight HA have not been performed, however, various literature sources suggest the use of a PES filter membrane would be the best option. There are a number of product alternatives available, such as the Steriflip-GP product SCGP00525 - see the link below to review this product.

      https://www.sigmaaldrich.com/US/en/product/mm/scgp00525

      Alternatively, HA can be added directly to the medium prior to filtration for tissue culture applications. See the link below to review a publication demonstrating this process:
