Aplicación

Hyaluronidase is an enzyme derived from bovine testes. It is used to remove the cumulus mass in the isolation of mouse embryos or from newly ovulated eggs, when preparing the eggs for in vitro culture.

Gonadotropins are used to superovulate 20 female mice. The mice are then mated and preimplantation stage embryos are retrieved and counted. The embryos are treated with hyaluronidase until the cumulus mass is dissociated from the embryos. The embryos are cultured, viewed daily and progress of the embryos is recorded.

Acciones bioquímicas o fisiológicas

Estas enzimas rompen aleatoriamente los enlaces glucosídicos β-N-acetilhexosamina [1→4] del ácido hialurónico, la condroitina y los sulfatos de condroitina.
La hialuronidasa degrada el hialuronano y se ha observado que su regulación no es apropiada durante la progresión del cáncer.

Definición de unidad

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).

Nota de preparación

Reconstitute 1 vial of hyaluronidase with 3 ml of M2 Medium (Product Nos. M 7167 or M 5910) or deionized water to obtain a 10 mg/ml stock solution. Dilute stock solution with M2 Medium to obtain a final working concentration of approximately 300 μg/ml.

Protocolos

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.
