Description

The 11B11 antibody reacts with mouse interleukin-4 (IL-4), a 14 kD cytokine. The 11B11 antibody is a neutralizing antibody. Mouse IL-4, also known as BCDF, BCGF-1 and BSF-1, is secreted by activated Th2 and natural killer T cells, and to a lesser extent by Th1 and mast cells. IL-4 is species-specific and promotes proliferation and differentiation of B cells. IL-4, in conjunction with other signals such as CD40, induces Ig isotype switching of B cells and the upregulation of surface MHC class II and CD23.

Applications Reported

For research use only, not for diagnostic or therapeutic use. The 11B11 antibody has been reported for use in ELISA capture, ELISPOT capture, neutralization of IL-4 bioactivity, IHC, and intracellular staining for flow cytometric analysis.

Applications Tested

The Functional Grade Purified 11B11 antibody has been tested by LAL assay to verify low endotoxin levels, by ELISA, and in bioassay for neutralization of mouse IL-4 bioactivity.

The 11B11 antibody at 0.125 ug/ml has been found to inhibit by 50% the biological effects of 1.0 ng/ml mouse IL-4 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 11B11 antibody has been tested as the capture antibody in a sandwich ELISA for analysis of mouse interleukin-4 (IL-4) in combination with the biotinylated BVD6-24G2 (13-7042) antibody for detection and recombinant mouse IL-4 (14-8041) 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.
