Description

The MD-1 antibody reacts with human, rhesus, cynomolgus and baboon interferon-gamma (IFN-γ), the signature Th1 cytokine, which is produced mainly by activated T cells, NK cells and B cells. IFN-γ is a dimeric protein. IFN-γ has antiviral and antiparasitic activities and also inhibits the proliferation of normal and transformed cells.

Applications Reported

For research use only, not for diagnostic or therapeutic use. The MD-1 antibody has been reported for use in intracellular flow cytometric analysis, cytokine neutralization, immunohistochemical staining, ELISA, and ELISPOT. (Fluorochrome conjugated MD-1 is recommended for use in intracellular flow cytometry.) (Please use Functional Grade purified MD-1, cat. 16-7317, in functional assays.)

Applications Tested

The MD-1 antibody has been tested as the capture antibody in a sandwich ELISA for analysis of human interferon-γ (IFN-γ) in combination with the biotinylated 4S.B3 (13-7319) antibody for detection and recombinant human IFN-γ (39-8319) as the standard. A suitable range of concentrations of this antibody for ELISA capture is 1-4 µg/ml. A standard curve consisting of doubling dilutions of the recombinant standard over the range of 1000 pg/ml - 8 pg/ml should be included in each ELISA plate.
The FG Purified format of the MD-1 antibody has been tested as the capture antibody in an ELISPOT assay (in conjunction with the biotinylated 4S.B3 antibody) and for neutralization of IFN-γ biological activity. A suitable range of concentrations of this antibody for ELISPOT capture is 1-4 µg/ml.
For in vitro neutralization, the MD-1 antibody at 30 ug/ml has been found to neutralize by 50% the effect of 1 ng/ml human IFN-γ. A more potent neutralizing antibody is clone NIB42.
