Description
The XMG1.2 antibody reacts with mouse interferon-γ. The XMG1.2 antibody is a neutralizing antibody. Mouse IFN-γ is a 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.
Applications Tested
The Functional Grade Purified XMG1.2 antibody has been tested by LAL assay to verify low endotoxin levels and has been tested for ELISA capture and in bioassay for neutralization of IFN-γ bioactivity.
The XMG1.2 antibody has been tested as the capture antibody in a sandwich ELISA for analysis of mouse Interferon-γ in combination with the biotin R4-6A2 (13-7312) antibody for detection and recombinant mouse IFN-γ (39-8311) as the standard. A suitable range of concentrations of this antibody for ELISA capture is 0.25 – 1.0 µg/ml. A standard curve consisting of doubling dilutions of the recombinant standard over the range of 2000 pg/ml - 15 pg/ml should be included in each ELISA plate. Detailed instructions for Cytokine Sandwich ELISA Using Matched Antibody Pairs can be found in the BestProtocols section.
For ELISPOT capture, the Functional Grade Purified AN-18 antibody is recommended.
