Recombinant Human FLT3LG, Thr27-Pro185, was produced in Sf 9 (baculovirus)-derived in an animal component free process under cGMP guidelines.
Lyophilized from a 0.2 μm filtered solution in PBS.
Measured in a cell proliferation assay using BaF3 mouse pro‑B cells transfected with mouse Flt-3. The ED50 for this effect is 0.2-1 ng/mL.
The specific activity of recombinant human Flt-3 Ligand is approximately 1.2 x 10^3 U/μg, which is calibrated against recombinant human Flt-3 Ligand WHO Standard (NIBSC code: 96/532).
Predicted Molecular Mass: 17.5 kDa
SDS-PAGE: 17-30 kDa, reducing conditions
N-terminal Sequence Analysis:
<0.01 EU per 1 μg of the protein by the LAL method.
