Il4 Rabbit Polyclonal Antibody

Specifications

Product Data
Applications	ELISA, WB
Recommend Dilution	Sandwich ELISA: To detect Murine IL-4 by sandwich ELISA (using 100 ul/well antibody solution) a concentration of 0.25 – 1.0 μg/ml of this antibody is required. This biotinylated polyclonal antibody, in conjunction with ProSci’s Polyclonal Anti-Murine IL-4 as a capture antibody, allows the detection of at least 0.2 – 0.4 ng/well of recombinant Murine IL-4. Western Blot To detect Murine IL-4 by Western Blot analysis this antibody can be used at a concentration of 0.1 - 0.2 ug/ml. When used in conjunction with compatible secondary reagents the detection limit for recombinant Murine IL-4 is 1.5 - 3.0 ng/lane, under either reducing or non-reducing conditions.

Background	IL-4 is a pleiotropic cytokine that regulates diverse T and B cell responses including cell proliferation, survival and gene expression. Produced by mast cells, T cells and bone marrow stromal cells, IL-4 regulates the differentiation of naive CD4+ T cells into helper Th2 cells, characterized by their cytokine-secretion profile that includes secretion of IL-4, IL-5, IL-6, IL-10, and IL-13, which favor a humoral immune response. Another dominant function of IL-4 is the regulation of immunoglobulin class switching to the IgG1 and IgE isotypes. Excessive IL-4 production by Th2 cells has been associated with elevated IgE production and allergy. Recombinant Murine IL-4 is a 13.5 kDa globular protein containing 121 amino acid residues.
