Description

Description générale

Hyaluronidase is a hyaluronic acid-metabolizing enzyme. It is found in the venoms of snake, honeybee and hymenoptera. Hyaluronidase degrades hyaluronic acid (HA), which enhances membrane permeability, lowers viscosity and increases tissue permeability. It enhances the diffusion of local anesthetics, lowers the size of myocardial infarction, improves the effects of anticancer drugs and prevents perineal trauma during spontaneous delivery.

Application

Hyaluronidase from sheep testes has been used:

• in flow cytometry
• in the isolation of putative spermatogonial stem cells (SSCs)
• to study the effects of magnetic stimulation in magnetic hydrogel properties
• in immunohistochemistry to visualize collagen type II distribution
• to expose group-III auditory neurons of Muller′s organ for patch-clamp recordings
• for the degeneration of hydrogels

Actions biochimiques/physiologiques

These enzymes randomly cleave β-N-acetylhexosamine-(1−4)-glycosidic bonds in hyaluronic acid, chondroitin, and chondroitin sulfates.

Définition de l'unité

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).

Forme physique

Lyophilized powder containing lactose
