General description

Hyaluronidase is present in high amount in testis as it aids fertilization of the mammalian egg. Mammalian hyaluronidase has a catalytic epidermal growth factor (EGF)-like domain and a C-terminal cysteine rich region.


Hyaluronidase has been used:
  • as a component of enzyme mix for the isolation of sertoli and germ cells from seminiferous tubules
  • in the pre-treatment of deparaffinized adenomas sections for immunohistochemistry
  • in the digestion of umbilical cord blood vessel for the generation of umbilical cord stromal stem cell lines

Biochem/physiol Actions

Hyaluronidase from sheep testis is commercially used to depolymerise hyaluronic acid and chondroitin-sulphate in connective tissue and cartilage respectively.
These enzymes randomly cleave β-N-acetylhexosamine-(1−4)-glycosidic bonds in hyaluronic acid, chondroitin, and chondroitin sulfates.

Unit Definition

One unit will cause a change in % transmittance at 600 nm of 0.330 per minute at pH 5.35 at 37 °C in a 2.0 mL reaction mixture (45 minute assay).
