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.
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.
The lot specific COA document can be found by entering the lot number above under the "Documents" section.

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.

Glycosaminoglycans are large linear polysaccharides constructed of repeating disaccharide units.
This procedure may be used for Hyaluronidase products.
在测定透明质酸酶活性时,使用了一种在600 nm处的比浊测定法进行测定。在pH 5.35、37 °C下,一单位的透明质酸酶活性可每分钟引起0.330的吸光值改变。
