Neutralization: To yield one-half maximal inhibition [ND50] of the biological activity of hIL-3(3.0 ng/mL), a concentration of 0.06 - 0.1 μg/mL of this antibody is required. ELISA: To detect hIL-3 by direct ELISA (using 100 l/well antibody solution) a concentrationof at least 0.5 μg/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 hIL-3. Western Blot: To detect hIL-3 by Western Blot analysis this antibody can be used at aconcentration of 0.1 - 0.2 μg/mL. Used in conjunction with compatible secondary reagentsthe detection limit for recombinant hIL-3 is 1.5 - 3.0 ng/lane, under either reducing ornon-reducing conditions. Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.

The pleiotropic IL3 (Interleukin 3) is a 15 kDa cytokine that is primarily secreted by activated T lymphocytes and stimulates the proliferation and differentiation of hematopoietic cells. IL3 acts in hematopoiesis by controlling the production, differentiation, and function of two related white cell populations of the blood, the granulocytes and the monocytes/macrophages. It induces granulocytes, macrophages, mast cells, stem cells, erythroid cells, eosinophils and megakaryocytes and is expressed by activated T cells, mast cells, and natural killer cells. IL3 not only supports growth of both pluripotent stem cells and the more differentiated committed progenitors, but it also stimulates the functional activity of some fully differentiated cells. IL3 has also been shown to protect mast cells from undergoing apoptosis.Synonyms: Hematopoietic growth factor, IL-3, MCGF, Mast cell growth factor, Multipotential colony-stimulating factor, P-cell-stimulating factor
