An efficacious large-scale alcohol-free plasma fractionation production process which produces a high-yielding, non-denatured, double viral-inactivated intravenous human immune gamma globulin (IgG) product. The process employs one or more salts from a group of salts comprising sodium citrate, sodium acetate, sodium gluconate, ammonium sulfate, sodium chloride, sodium sulfate and ammonium chloride in two initial fractionation steps, followed by diafiltration to remove those salts employed. A process which employs alcohol via the process of the disclosed inventive method is also disclosed. |
