The KRISHZYME Hyaluronidase Assay kit uses a two-step turbidimetric reaction to measure hyaluronidase activity by the amount of hyaluronic acid that is hydrolyzed. A stop reagent halts the enzymatic reaction and forms turbidity with any residual hyaluronic acid in the well. The decrease in turbidity at 600 nm is directly proportional to hyaluronidase activity in the sample.
Hyaluronidase is a family of enzymes that degrade hyaluronic acid by catalyzing the hydrolysis of hyaluronan, a constituent of the interstitial barrier. Hyaluronidase lowers the viscosity of hyaluronan, thereby increasing tissue permeability. It is, therefore, used in medicine in conjunction with other drugs to speed their dispersion and delivery.
