Tosyl compounds
Sigma Aldrich Fine Chemicals Biosciences Chitinase Assay Kit Fluori
The kit assay is based on the enzymatic hydrolysis of chitinase substrates. This enzymatic hydrolysis releases 4-methylumbelliferone (4MU) which upon ionization in basic pH can be measured fluorimetrically at an excitation wavelength of 360 nm and an emission wavelength of 450 nm. The use of fluorimetric substrates provides a very sensitive detection system.
