Proteolytic activity in liver cells from mouse, rat, Ehrlich ascites carcinoma bearing mouse and in Ehrlich ascites carcinoma cells.

The activity of intracellular proteinases from Ehrlich ascites carcinoma bearing mice were compared with that from liver cells of normal mice and rats. The activity of intracellular proteinases was measured in the supernatant of Ehrlich ascites carcinoma cells homogenate. The activity of intracellular proteinases in normal mouse and normal rat liver were different at pH 3.
