Aplicação

Hyaluronic acid sodium salt from bovine vitreous humor has been used:
  • as a component for the generation of artificial synovial fluid[1]
  • to investigate its role in inducing oxidative stress and interleukin 8(IL-8) production in human nasal RPMI 2650 cells[2]
  • to test its effect on B cell proliferation[3]
  • as a substrate in neuraminidase assay of morbilliviruses virus[4]

Ações bioquímicas/fisiológicas

High molecular mass polymer composed of repeating dimeric units of glucuronic acid and N-acetyl glucosamine which forms the core of complex proteoglycan aggregates found in extracellular matrix.
Hyaluronic acid (HA) is abundantly present in the bovine vitreous humor. It corresponds to a molecular weight of 69293.9Da and has an isoelectric pH of 5.82. Bovine HA has high levels of endotoxins and it polydisperse with DNA and RNA contaminants.[5] The enzyme HA synthases at the plasma membrane (HASs) aids in the synthesis of circulatory HA. HA is implicated in many physiological processes including inflammation, immune regulation, adhesion, embryo development and tumor progression.[6]

Glycosaminoglycans are large linear polysaccharides constructed of repeating disaccharide units.

Protocolos

To measure hyaluronidase activity, a turbidimetric determination assay is used at 600 nm. One unit of hyaluronidase activity will cause a change in absorbance of 0.330 per minute at pH 5.35 at 37 °C.

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.

  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
