Characterization of Monoclonal Antibody Specific for Human Alpha Interferon

Abstract

A mouse hybridoma cell line has been isolated, which secretes a monoclonal antibody specific of human leukocyte (alpha) interferon. The antibody secreted by the hybridoma belongs to the IgG1 class. It neutralizes biological activities (cellular and antiviral) of alpha interferon. Mass production of the antibody in ascitic fluid has been obtained. A convenient method of purification of the IgG from the ascitic fluid on DEAE-Trisacryl M is described.
