Description: The R4-6A2 antibody reacts with mouse interferon-γ (IFN-γ ), a homodimeric 15-20 kDa cytokine secreted by Th1 cells. The R4-6A2 antibody is a neutralizing antibody. IFN-γ is an ~20 kDa factor produced by activated T, B and NK cells and is an anti-viral and anti-parasitic cytokine. IFN-γ in synergy with other cytokines, such as TNF-α, inhibits proliferation of normal and transformed cells. Immunomodulatory effects of IFN-γ are exerted on a wide range of cell types expressing the high affinity receptors for IFN-γ. Glycosylation of IFN-γ does not affect its biological activity.
