Abstract
Summary
Egg-white antitrypsin not only fails to prevent but actually stimulates the digestion of plasma by cells cultivated in vitro. The presence of even low concentrations of antitrypsin inhibits tissue-culture growth but does not interfere with normal plasma coagulation. The antitrypsin preparations shown to be ineffective in tissue cultures strongly inhibit the proteolytic activity of crystalline trypsin in test-tube experiments.
