Anti-IFN gamma antibodies detect the protein encoded by the gene IFNG, or 'interferon gamma' in humans. The 166-amino acid protein is a member of the Type II (or gamma) interferon family and antibodies to the IFN gamma antigen may be useful for studying cytokine signaling. Cellular localization is predicted to be secreted. Glycosylation sites have been reported. Antibodies to the IFN gamma antigen may be useful for studying cytokine signaling.
