Active Site Titration of Horse Liver Alcohol Dehydro-Genase by Dual Wavelength Specthophotomethy

Abstract

A simple dual wavelength spectrophotometric method for determining the active site concentration of horse liver alcohol dehydrogenase is described. The method is rapid, sensitive, accurate and requires minute amounts of enzyme. A comparison between this new application of the dual wavelength technique and the conventional methods, ordinary photometry and spectrofluorometry is furthermore discussed.
