Neutralization. ELISA: To detect Rat IL-4 by direct ELISA (using 100l/well antibody solution) a concentration of atleast 0.5g/mL of this antibody is required. This antigen affinity purified antibody, inconjunction with compatible secondary reagents, allows the detection of 0.2-0.4 ng/wellof recombinant Rat IL-4. Western Blot: To detect Rat IL-4 by Western Blot analysis this antibody can be used at a concentration of0.1-0.2 μg/mL. Used in conjunction with compatible secondary reagents the detection limitfor recombinant Rat IL-4 is 1.5-3.0 ng/lane, under either reducing or non-reducingconditions. Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.

IL4 is a pleiotropic cytokine produced by activated T cells, mast cells and basophils. It is a ligand for Interleukin 4 receptor. The Interleukin 4 receptor also binds to IL13, which may contribute to many overlapping functions of this cytokine and IL13. IL4 elicits many different biological responses, but has two dominant functions. The first is regulating differentiation of naive CD4+ T cell to the Th2 type. Th2 cells produce IL4, IL5, IL10 and IL13, which tend to favor a humoral immune response while suppressing a cell mediated immune response controlled by Th1 cells. STAT6, a signal transducer and activator of transcription, has been shown to play a central role in mediating the immune regulatory signal of this cytokine. The second is regulating IgE and IgG1 production by B cells. Two alternatively spliced transcript variants of this gene encoding distinct isoforms have been reported.Synonyms: B-cell stimulatory factor 1, BSF1, Binetrakin, IL-4, Lymphocyte stimulatory factor 1, Pitrakinra
