Abstract

Summary

An antiserum to immune T-type mouse interferon was prepared in rabbits by repeated injections of interferon, induced by phytohaemagglutinin (PHA) in mouse spleen cells and purified to 1 × 10 units/mg protein. The antiserum neutralized mouse interferons synthesized in response to several T mitogens and Brucella organisms, and also the type II interferon present in the serum of BCG-sensitized mice after an injection of the specific antigen, tuberculin. All these interferons are thus antigenically related; they are also all unstable at pH 2. In contrast, the antiserum did not neutralize interferons induced by West Nile virus (WNV) and Newcastle disease virus (NDV) , or by lipopolysaccharide and Brucella organisms ; all these interferons are stable at pH 2. It also failed to neutralize a non-glycosylated virus interferon prepared in the presence of tunicamycin.
