[Gelatinase activity of protein fractions obtained by electrophoresis in polyacrylamide gel].

The modification of a method of determination gelatinolytic activity in protein fractions obtained by one and two-dimensional polyacrylamide gel electrophoresis is presented. The presence of a fraction 115-125 kD among human proteins of cortex matter and glomerulus of kidney and also in myocardium having gelatinolytic activity is demonstrated.
