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.

Applications Reported

For research use only, not for diagnostic or therapeutic use. The R4-6A2 antibody has been reported for use in immunoblotting (WB), ELISPOT, and ELISA.

Applications Tested

The biotinylated R4-6A2 antibody has been tested as the detection antibody in a sandwich ELISA for analysis of mouse IFNg (Interferon-gamma, IFN-g) in combination with the purified AN-18 (14-7313) antibody or the purified XMG1.2 (14-7311) antibody for capture and recombinant mouse IFNg (39-8311) as the standard. A suitable range of concentrations of this antibody for ELISA detection is 0.5-2 µg/ml.
A standard curve consisting of doubling dilutions of the recombinant standard over the range of 200 pg/ml - 1.6 pg/ml (AN-18 assay) or 2000 pg/ml - 15 pg/ml (XMG1.2 assay) should be included in each ELISA plate.
