Product Data
Applications ELISA, WB
Recommend Dilution Direct ELISA: To detect Mouse IL-4 by direct ELISA (using 100 μl/well antibody solution) a concentration of 0.25-1.0 μg/ml of this antibody is required. This biotinylated polyclonal antibody, in conjunction with compatible secondary reagents, allows the detection of at least 2000-4000 pg/well of recombinant Mouse IL-4.
Sandwich ELISA: To detect Mouse IL-4 by sandwich ELISA (using 100 μl/well antibody solution) a concentration of 0.25-1.0 μg/ml of this antibody is required. This biotinylated polyclonal antibody, in conjunction with Polyclonal Anti-Murine IL-4 (Cat.-No PP011P) as a capture antibody, allows the detection of at least 0.2-0.4 ng/well of recombinant Mouse IL-4.
Western Blot: To detect Mouse IL-4 by Western Blot analysis this antibody can be used at a concentration of 0.1-0.2 µg/ml. Used in conjunction with compatible secondary reagents the detection limit for recombinant Mouse IL-4 is 1.5-3.0 ng/lane, under either reducing or non-reducing conditions.

Gene Name interleukin 4
Background 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 naïve 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 IL-4, BSF1, Lymphocyte stimulatory factor 1, Binetrakin, Pitrakinra
