Biochem/physiol Actions

这些酶可随机裂解透明质酸、软骨素和硫酸软骨素中的 β-N-乙酰己糖胺-[1→4] 糖苷键。
透明质酸酶可降解透明质酸，并已发现可在癌症进展期间会被不适当地调节。

Preparation Note

由无菌灌装的I-S型溶液制备。

Other Notes

在 37 ºC、pH 5.35 条件下，一单位每分钟可降解 0.75 μg 多糖透明质酸（通过比浊吸光度测量(λ: 600nm)，与 BSA 复合 45 分钟后测量）。

实验方案

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.
