DescriptionDescription: 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: This 11B11 antibody has been reported for use in cytokine neutralization, ELISPOT, and ELISA cap.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 μg/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. Please refer to Best Protocols for more information.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 (cat. 13-7042) antibody for detection and recombinant mouse IL-4 (cat. 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.Endotoxin: Less than 0.001 ng/ug antibody as determined by the LAL assay.Storage and handling: Use in a sterile environment.Filtration: 0.2μm post-manufacturing filtered.Purity: Greater than 90%, as determined by SDS-PAGE.Endotoxin Level: Less than 0.001 ng/μg antibody, as determined by LAL assay.Aggregation: Less than 10%, as determined by HPLC.
