The sequence of the first five N-terminal amino acids was determined and was found to be Thr-Gln-Asp-Cys-Ser.
The ED50 range=0.5-1.0 ng/ml corresponding to a specific activity of 1-2MUnits/mg, calculated by the dose-dependant stimulation of the proliferation of human OCMI-AML5 cells.
The protein was lyophilized with no additives.
Sterile Filtered White lyophilized (freeze-dried) powder.
Greater than 95.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
It is recommended to reconstitute the lyophilized Flt3-L in sterile 18MΩ-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Lyophilized Flt3-Ligand although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution Flt3-Ligand should be stored at 4oC between 2-7 days and for future use below -18oC.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
Fms-related tyrosine kinase 3 ligand, FLK2, STK1, CD135, Stem Cell Tyrosine Kinase 1, FLT3LG, Flt3.
