|7017: Recombinant Murine FMS-Link Tyrosine Kinase-3 Ligand (rHuFLT-3L)|
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 Murine Flt3-Ligand produced in E.Coli is a non-glycosylated, polypeptide chain containing 144 amino acids and having a molecular mass of 16431 Dalton.
Lyopohilized with no additives.
It is recommended to reconstitute the lyophilized product with sterile water at a concentration of 0.1 mgs/ml, which can be further diluted into other aqueous solutions.
Lyophilized product is very stable at -20 degrees. Reconstituted material should be aliquoted and frozen at -20. It is recommended to add a carrier protein (0.1% HSA or BSA) for long term storage.
rmFlt3-Ligand is fully biologically active when compared to standard. The activity is determined by the ability to generate CD11c+ splenic dendritic cells in vivo in C57B1/6-12 week female mice. To obtain the desired affect, mice were treated with approximately 25ug of flt3-ligand once daily for 9 consecutive days via intraperitoneal injection.
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.
