Human .alpha..sub.1 -antichymotrypsin (ACT) can be purified from solutions containing human .alpha..sub.1 -proteinase inhibitor (PI) and antithrombin III (AT-III) using chromatography adsorption steps at carefully controlled pH and conductivity. The separated ACT retains in vitro inhibitory capacity and has potential therapeutic use.
