Product Description |
Recombinant Human IL-3 Protein is expressed from E.coli without tag.It contains Ala20-Phe152. |
Product Background |
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. This CSF induces granulocytes, macrophages, mast cells, stem cells, erythroid cells, eosinophils and megakaryocytes. |
