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.\u003c\/p\u003e\u003cp\u003eApplications Reported: This 11B11 antibody has been reported for use in intracellular staining followed by flow cytometric analysis.\u003c\/p\u003e\u003cp\u003eApplications Tested: This 11B11 antibody has been tested by intracellular staining followed by flow cytometric analysis of mouse Th2-polarized splenocytes using the Intracellular Fixation \u0026amp; Permeabilization Buffer Set (\u003ca href=\"https:\/\/www.thermofisher.com\/order\/catalog\/product\/88-8824-00\"\u003eProduct # 88-8824-00\u003c\/a\u003e) and protocol.

This may be used at less than or equal to 0.25 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells\/test.
