Protease Colorimetric Detection Kit

Properties

• 储存温度: 2-8°C

Description

应用

The Protease Colorimetric Detection Kit is designed for the accurate quantitation of protease activity. The method is based on the cleavage of casein into trichloroacetic acid-soluble peptides containing tyrosine and tryptophan residues. These peptides react with Folin-Ciocalteu reagent to give a characteristic blue color that can be measured at 660 nm.

适用性

Detection limit: 0.1 unit/ml (approx. 2 μg) trypsin with a 10 minute incubation time.

联系

For greater sensitivity or for detection of trace protease activity, the Protease Fluorescent Detection kit (PF0100) is recommended.

数量

Supplied with sufficient reagents to perform 200 one mL assays.

分析说明

This kit has been tested for detection of all four proteolytic classes (serine, apartic, cysteine and metalloproteinases).
