Abstract

Isoenzyme patterns of an enzyme in biological fluids, extracts, and/or excretions are quantitatively determined by precipitating at least 90% of an isoenzyme antigen with a corresponding heterologous antiserum and comparing the remaining enzyme activity with the total activity with the use of a conventional agent for enzyme activity determination.
