Human FLT3 Ligand Recombinant

FLT-3 ligand promotes long- term expansion and differentiation of human pro-B-cells in the presence of IL-7 or in combination of IL-7 and IL-3.The human FLT-3 ligand also stimulates the proliferation of cells expressing murine FLT-3 receptors. In combination with SCF and IL-3, FLT-3 ligand can cause expansion of cells with the marker spectrum CD34 (+) CD38 (-) . Alone, FLT-3 ligand 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. flt-3 ligand only has marginal effects on progenitors for erythroid cells and megakaryocytes.

Reconstitute at 0.1-1.0 mg/ml in distilled water. This solution can then be diluted into other buffers. To maximize product collection from vial surface, vortex briefly and then spin down to recollect the liquid.

The lyophilized protein is stable for at least 2 years from date of receipt when stored at -20°C. Upon reconstitution, store in working aliquots at +4°C for up to one month, or at -20°C for up to six months, in the presence of a carrier protein. Avoid repeated freeze/thaw cycles.
