Ces enzymes coupent de façon aléatoire les liaisons glycosidiques β-N-acétylhexosamine-[1→4] dans l′acide hyaluronique, la chondroïtine et les sulfates de chondroïtine.
L′hyaluronidase dégrade l′hyaluronane et elle semble être régulée de façon anormale lors de la progression du cancer.

  1. How does the storage temperature relate to shipping conditions?

    The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment. See Shipping and Storage for more information.

  2. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  3. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  4. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page. You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers.

  5. What is the Department of Transportation shipping information for this product?

  6. Can stock solutions of Product H3884, Hyaluronidase from bovine testes, be stored frozen after reconstitution?

    Although Sigma-Aldrich has not tested the stability of stock solutions of Product H3884, Hyaluronidase from bovine testes, several publications cite storage of solutions of H3884 at -20 °C:1.  Campbell, Keith H.S, "Transgenic Sheep form Cultured Cells", from Transgenesis Techniques: Principles and Protocols, Methods Mol. Biol., 180, 289-301 (2002).  A 1500 IU/mL stock solution was stored in 20 mL aliquots at -20 °C.2.  Marschall, S. and de Angelis, M.H., "In Vitro Fertilization/Cryopreservation", from Transgenic Mouse: Methods and Protocols, Methods in Molecular Biology, 209, pp. 35-50. Humana Press (2003).  1 mg/mL stock solutions in M2 medium or water, sterile-filtered (0.22 mm filter) can be stored in aliquots at -20 °C.
