Known to bind to cells that express the tyrosine kinase receptor, FLT3LG promotes long-term expansion and differentiation of human pro-B cells. Human FLT3LG also stimulates the proliferation of cells expressing murine FLT-3 receptors. In combination with SCF and IL3, FLT3LG can cause expansion of cells with the marker spectrum CD34(+)/CD38(-). Alone, FLT3LG supports the survival of precursors in the lineage of blood-forming cells such as CFU-GM, CFU-GEMM, and the very primitive high proliferative potential colony-forming cells, HPP-CFC. FLT3LG has only marginal effects on progenitors for erythroid cells and megakaryocytes. Recombinant Human FLT3LG is a glycosylated, monomeric protein (with intra-chain disulfide bonds) that runs at approximately 26kD on a reducing SDS-PAGE.||Source:|Recombinant protein corresponding to human FLT3 Ligand expressed in CHO cells.||Molecular Weight:|~17kD||Biological Activity:|The ED50 as determined by the dose-dependent stimulation of the proliferation of Human AML5 cells was 1ng/mL.||Endotoxin:|<1EU/ug (LAL)||Storage and Stability:|Lyophilized powder may be stored at -20°C.
