IL3, also known as interleukin 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, it also affects the functional activity of mature mast cells, basophils, eosinophils and macrophages. Recombinant protein corresponding to aa27-166 from mouse IL3, fused to His-tag at C-terminal expressed in insect cell.
