Product Description

Hyaluronidase is a glycoprotein isolated from bovine testes that degrades hyaluronan (HA) polymers (1). This enzyme hydrolyzes the endo-N-acetylhexosaminic bonds of hyaluronic acid, chondroitinsulfuric acid A, and chondroitinsulfuric acid C to tetrasaccharide rich oligosaccharides (2). Studies have shown that hyaluronidases have the potential for clinical utility as both biomarkers and therapeutic targets when looking at a variety of cancers (1). Hyaluronidase is an effective enzyme for tissue dissociation (3,4).
Activity Greater than or equal to 3,000 units per mg dry weight

Unit Definition: One unit is based on the change in absorbency (turbidity) at 540 nm of an internal standard assayed concurrently with each lot. Internal standard replaces USP/NF reference no longer available.
