| Gene ID | 2323 |
| Accession | P49771 |
| Alternative Name | Fms-related tyrosine kinase 3 ligand, FLT3 ligand, FLT3LG, FLT3L |
| Species | Human |
| Source | E. coli |
| Description | 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. |
| Accession | P49771 |
| Functions | The ED50 as determined by the dose-dependent stimulation of the proliferation of Human AML5 cells was found to be in the range of 1.0 ng/mL |
| Formulation | Lyophilized from a 0.2 ?m filtered PBS solution pH 7.0 |
| Solubility | A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers. |
| Appearance | Lyophilized Powder |
| Molecular Weight | 17.8 |
| Purity | >95% as determined by SDS-PAGE |
| Concentration | <1.0 EU/μg of recombinant protein as determined by the LAL method |
| Shipping Condition | Ambient Temperature |
| Storage Condition | The lyophilized protein is stable for at least one year from date of receipt at -70?C. Upon reconstitution, this cytokine can be stored in working aliquots at 2? - 8?C for one month, or at -20?C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles. |
