IL3, Murine

GoldBio growth factors are manufactured for RESEARCH USE ONLY and cannot be sold for human consumption!Recombinant Murine Interleukin 3IL-3Mast-cell Growth Factor, MCGFMulti-CSFP-cell Stimulating FactorInterleukin 3 is a pleiotropic factor produced primarily by activated T cells that can stimulate the proliferation and differentiation of pluripotent hematopoietic stem cells as well as various lineage committed progenitors. In addition, IL3 also affects the functional activity of mature mast cells, basophils, eosinophils and macrophages. Because of its multiple functions and targets, it was originally studied under different names, including mast cell growth factor, P-cell stimulating factor, burst promoting activity, multicolony stimulating factor, thy-1 inducing factor and WEHI-3 growth factor.In addition to activated T cells, other cell types can also produce IL3, such as human thymic epithelial cells, activated murine mast cells, murine keratinocytes and neurons/astrocytes. At the amino acid sequence level, mature human and murine IL3 share only 29% sequence identity. Consistent with this lack of homology, IL3 activity is highly species-specific and human IL3 does not show activity on murine cells.Formulation: Sterile filtered white lyophilized powder.
