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 PE conjugated 11B11 antibody is offered in 2 formats:
- µg size: has been tested by intracellular staining with flow cytometric analysis and can be used at less than or equal to 0.125 μg/million cells in 100 ul staining volume. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
- test size: has been pre-titrated and tested by intracellular staining with flow cytometric analysis and can be used at 20 μl per million cells in a 100 μl total staining volume. The pre-titrated test size contains 0.2% BSA.
