Name : Human CD117 Protein
Product Source :
Recombinant Human CD117 Protein is expressed from HEK293 with hFc tag at the C-Terminus. It contains Gln26-Pro520.[Accession | P10721-2]
Molecular Weight :
The protein has a predicted MW of 82.46 kDa. Due to glycosylation, the protein migrates to 100-130 kDa based on Tris-Bis PAGE result.
Endotoxin Level :
Less than 1EU per μg by the LAL method.
Purity :
> 95% as determined by Tris-Bis PAGE
Formulation :
Lyophilized from 0.22μm filtered solution in 20mM PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution :
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
Storage and Stability :
-20 to -80°C for 12 months as supplied from date of receipt.-80°C for 3-6 months after reconstitution.2-8°C for 2-7 days after reconstitution.Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Product Concentration :
Tris-Bis PAGE Human CD117 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. ELISA Data Immobilized Human CD117, hFc Tag at 0.5μg/ml (100μl/well) on the plate. Dose response curve for Biotinylated Anti-CD117 Antibody, hFc Tag with the EC50 of 12.7ng/ml determined by ELISA (QC Test). ELISA Data Immobilized Human SCF, No Tag at 1μg/ml (100μl/well) on the plate. Dose response curve for Human CD117, hFc Tag with the EC50 of 12.4ng/ml determined by ELISA.
Background :
The c-kit proto-oncogen (CD 117) has been shown to be present in several cell types including normal and neoplastic hemopoietic cells. Among normal BM cells, CD117 expression has been found in about half of the CD34 precursors including progenitors committed to the erythroid, granulo-monocytic, and megakaryocytic cell lineages.
Synonyms :
SCFR; PBT; CD117; ckit; c-kit; EC 2.7.10; EC 2.7.10.1; KIT
