The enzyme activity expressed as
katal is related to the type of substrate, to the nature of the enzyme and to
the experimental conditions. In the following paragraphs, a tentative
correlation between the different types of units and the enzyme activity with
Chromogenix substrates is reported. The purpose is to help the researchers in
developing chromogenic methods, by using such information as a starting point.
The conversion factors, have been taken from journal articles or from laboratory results within the Chromogenix R&D department, thus the consultation of such references or of the assay conditions reported in the kinetic tables is recommended.
