Description

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.

Application

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.

Other Notes

One unit will degrade 0.75 μg of the polysaccharide hyaluronic acid per minute at pH 5.35 at 37 ºC (as measured by turbidimetric absorbance (λ: 600nm) when complexed with BSA after 45 minutes).

Protocols

透明质酸酶的酶法测定 (3.2.1.35)

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。

Enzymatic Assay of Hyaluronidase (3.2.1.35)

To measure hyaluronidase activity, a turbidimetric determination assay is used at 600 nm. One unit of hyaluronidase activity will cause a change in absorbance of 0.330 per minute at pH 5.35 at 37 °C.
