Measured in a cell proliferation assay using BaF3 mouse proB cells transfected with mouse Flt3. The ED50 for this effect is typically 2-11 ng/mL.
A DNA sequence encoding the human FLT3LG (P49771-1) (Thr27-Pro185) was expressed, with a polyhistidine tag at the N-terminus.
The recombinant human human FLT3LG consists of 175 amino acids and predicts a molecular mass of 20.2 KDa. It migrates as an approximately 27 KDa band in SDS-PAGE under reducing conditions.
Lyophilized from sterile 20mM Tris, 500mM NaCl, pH 7.4
1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us
for any concerns or special requirements.Please refer to the specific buffer information in the hard copy of CoA.
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
Stability & Storage
Samples are stable for up to twelve months from date of receipt at -70℃
Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.
FLT3L, also known as flt3 ligand, is a small molecule that acts as a growth factor that increases the number of immune cells by activating the hematopoietic progenitors. In vivo, FLT3L also induces the mobilization of the hematopoietic progenitors and stem cells. This may help the system to kill cancer cells. Dendritic cells (DCs) provide the key link between innate and adaptive immunity by recognizing pathogens and priming pathogen-specific immune responses. FLT3L controls the development of DCs and is particularly important for plasmacytoid DCs and CD8 -positive classical DCs and their CD103 -positive tissue counterparts.
