Description

General description

Hyaluronidase is present in high amount in testis as it aids fertilization of the mammalian egg.[1] Mammalian hyaluronidase has a catalytic epidermal growth factor (EGF)-like domain and a C-terminal cysteine rich region.[2]

Application

Hyaluronidase has been used:

• as a component of enzyme mix for the isolation of sertoli and germ cells from seminiferous tubules[3]
• in the pre-treatment of deparaffinized adenomas sections for immunohistochemistry[4]
• in the digestion of umbilical cord blood vessel for the generation of umbilical cord stromal stem cell lines[5]

Packaging

500 mg in poly bottle

1 g in poly bottle

Biochem/physiol Actions

Hyaluronidase from sheep testis is commercially used to depolymerise hyaluronic acid and chondroitin-sulphate in connective tissue and cartilage respectively.[1]

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).
