Active Recombinant Human Fms-related Tyrosine Kinase 3 Lligand

• Cat.No.: FLT3LG-935H
• Product Overview: This ligand binds to Fms-Like Tyrosine Kinase-3 (FLT-3).Human FLT3 ligand also stimulates the proliferation of cells expressing murine FLT-3 receptors. The effects of FLT-3 ligand are synergized by coexpression of G-CSF, GM-CSF, M-CSF, IL3 and SCF. FLT-3 ligand promotes long-term expansion and differentiation of human pro-B-cells in the presence of IL7 or in combination of IL7 and IL3. Recombinant Human Flt3-Ligand produced in E.Coli is non-glycosylated, polypeptide chain containing 155 amino acids and having a molecular mass of 17605 Dalton.

Specification

• Cat. No.: FLT3LG-935H
• Description: Fms-related tyrosine kinase 3 ligand (FLT3LG) is a protein which in humans is encoded by the FLT3LG gene. Flt3 ligand (FL) is a hematopoietic four helical bundle cytokine. It is structurally homologous to stem cell factor (SCF) and colony stimulating facor 1 (CSF-1).
• Species: Human
• Source: E.coli
• Form: Lyophilized with no additives.
• Purity: Purity Greater than 98% as determined by: Analysis by RP-HPLC. Reducing and non-reducing SDS-PAGE.
• Bio-activity: rHuFlt3-Ligand is fully biologically active when compared to standard. The ED50, calculated by the dose-dependant stimulation of the proliferation of human AML5 cells is expected in a range of 0.6-1.0ng/ml.
• Physical Appearance: Sterile Filtered white lyophilized (freeze-dried) powder.
• Solubility: Centrifuge vial before opening. When reconstituting the product, gently pipet and wash down the sides of the vial to ensure full recovery of the protein into solution. It is recommended to reconstitute the lyophilized product with sterile water at a concentration of 0.1 mg/ml, which can be further diluted into other aqueous solutions.
• Purity Greater than 98% as determined by: Analysis by RP-HPLC. Reducing and non-reducing SDS-PAGE.
• Protein Content determined by: UV spectroscopy at 280 nm. Analysis by RP-HPLC calibrated against a known standard. Quantitation on SDS-PAGE against a known standard.
