The Flt-3 (fms-like tyrosine kinase) receptor, also named Flk-2 (fetal liver kinase) and Stk-1(stem cell tyrosine kinase) is a 130-155 kDa member of the class III subfamily of receptor tyrosine kinases that also includes KIT, the receptor for SCF and FMS, the receptor for M-CSF. Within ECD human Flt-3 shares 85% and 82% aa sequence identity with mouse and rat Flt-3. Flt-3 expression has been detected in various tissues, including placenta, gonads, and tissues of nervous and hematopoietic origin. Among hematopoietic cells, the expression of Flt-3 was found to be restricted to the highly enriched stem/progenitor cell populations.

表達區(qū)間及表達系統(tǒng)(Source) |
Recombinant Human FLT3 / Flk-2 Protein is expressed from HEK293 Cells with His tag and Avi tag at the C-terminal. It contains Asn27-Asn541. |
分子量(Molecular Weight) |
Approximately 61.2 kDa. Due to glycosylation, the protein migrates to 80-105 kDa based on Tris-Bis PAGE result. |
外觀(Physical Appearance) |
Sterile Filtered White lyophilized (freeze-dried) powder. |
純度(Purity) |
> 95% as determined by SDS-PAGE and HPLC |
活性(Activity) |
ELISA Data: Immobilized Human FLT3, His Tag at 0.5 μg/mL (100 μL/Well) on the plate. Dose response curve for Human FLT3 Ligand, hFc Tag with the EC50 of 0.1 μg/mL determined by ELISA. |
內(nèi)毒素(Endotoxin) |
< 1.0 EU per 1μg of the protein by the LAL method. |
制劑(Formulation) |
Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. |
復溶(Reconstitution) |
Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/mL` is recommended (usually we use 1 mg/mL solution for lyophilization). Dissolve the lyophilized protein in distilled water. |
運輸與保存方法
