Hyaluronidase, Bovine, Highly Purified (EC 3.2.1.35, Bovine testes)

Hyaluronidase catalyzes the random hydrolysis of 1,4-linkages between 2-acetamido-2-deoxy-beta-D-glucose and D-glucose residues in hyaluronate. Hyaluronate 4-glycanohydrolase (EC 3.2.1.35) catalyzes the depolymerization of mucopolysaccharides, hyaluronic acid, and the chondroitin sulfates A and C. The enzyme is widely distributed in animal tissues but is found in great concentrations in the bovine and ovine testes. It is also produced by a number of bacteria. Hyaluronidase from bovine testes has a molecular weight of 55,000. Purified hyaluronidase is used clinically for the intradermal administration of large volumes of fluid when intravenous injections are contraindicated. The enzyme is administered prior to or simultaneously with the fluid and it facilitates absorption of the fluid. Activity (USP/NF units/mg dw): >3000 U/mg, Absorbance (A280@mg/ml): As Reported, Unit Definition: One unit is based on the change in absorbency (turbidity) at 540nm of an internal standard. Quality Control: SDS-PAGE, Storage and Stability: Lyophilized powder may be stored at -20°C. Stable for 6 months after receipt. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Prepare fresh before use. Certificate of Origin: The raw animal product (bovine glands, organs and tissue) used in the manufacturing of Hyaluronidase is derived from materials of USDA-approved origin. It was collected in USDA or equivalent approved facilities and inspected to be free of disease.
