Abstract
The instant invention provides novel and effective methods of isolating alpha-1-antitrypsin from cryo-poor plasma and formulating it into therapeutic products. This invention achieves higher yields and a superior quality of alpha-1-antitrypsin. Alpha-1-antitrypsin is isolated from cryo-poor plasma, using one or more salts selected from a group comprising sodium citrate, sodium acetate, sodium gluconate, ammonium sulfate, sodium chloride, sodium sulfate and ammonium chloride in two fractionation steps, followed by diafiltration to remove those salts employed.
