Abstract
A method for stabilizing an alkanol amine buffer against substantial degradation so that enzyme activity can be optically determined in such a buffer is described. Stabilization is achieved by adding a stabilizing effective amount of a stabilizing agent to the buffer wherein the stabilizing agent (i) does not inhibit enzyme activity and (ii) does not interfere substantially with the optical determination in the wavelength region of measurement.
