Description

The JES6-1A12 antibody reacts with mouse interleukin-2 (IL-2). The JES6-1A12 antibody is a neutralizing antibody. Mouse IL-2 (also known as TCGF) is a 17 kDa factor produced mainly by activated CD4+ T cells. IL-2 induces cell cycle progression of resting cells in an antigen non-specific manner and allows clonal expansion of activated T cells. IL-2 also acts on activated B cells, monocytes, NK cells, LAK cells, and on oligodendroglial cells in vitro. In addition, IL-2 plays a role in hematopoiesis, tumor surveillance and anti-inflammatory reactions, and hence is a central regulator of the immune response. Non-glycosylated IL-2 is biologically active.

Applications Reported

For research use only, not for diagnostic or therapeutic use. The JES6-1A12 antibody has been reported for use in ELISA capture, ELISPOT capture, neutralization of IL-2 bioactivity, IP, and intracellular staining.

Applications Tested

The Functional Grade Purified JES6-1A12 antibody has been tested by LAL assay to verify low endotoxin levels, by ELISA, and in bioassay for neutralization of mouse IL-2 bioactivity.

The JES6-1A12 antibody at 0.250 ug/ml has been found to inhibit by 50% the biological effects of 1.0 ng/ml mouse IL-2 in a CTLL-2 cell proliferation assay. Detailed information and protocols about cytokine bioassays and in vitro cytokine neutralization using antibodies can be found in the BestProtocols section.

The JES6-1A12 antibody has been tested as the capture antibody in a sandwich ELISA for analysis of mouse Interleukin-2 (IL-2) in combination with the biotin JES6-5H4 (13-7021) antibody for detection and recombinant mouse IL-2 (14-8021) 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 500 pg/ml - 4 pg/ml should be included in each ELISA plate.
