title: Undegraded human immunoglobulin for intravenous use.
abstract: A report is presented on the development and the properties of a nondegraded human immunoglobulin preparation suitable for intravenous administration. Intravenous tolerance is achieved by elimination of anticomplementary activity through modification with beta-propiolactone. The natural antibody characteristics, such as antibody activity, molecular weight, and half-life, are retained. The findings presented open up new perspectives for an extension of the range of indication for intravenous immunoglobulin.
