Invitrogen™ IL-2 Monoclonal Antibody (JES6-1A12), Functional Grade, eBioscience™, Invitrogen™

Rat Monoclonal Antibody

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: The JES6-1A12 antibody has been reported for use in ELISA capture, ELISPOT capture, neutralization of IL-2 bioactivity, and IP. 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 μg/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.
