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 non-glycosylated, monomeric protein with intra-chain disulfide bonds.
Product Name- Recombinant Human FLT3 Ligand (FLT3LG)
Aliases- Fms-related tyrosine kinase 3 ligand, FLT3 ligand, FLT3LG, FLT3L
Formulation- Lyophilized from a 0.2 µm filtered PBS solution pH 7.0
