Name : Human IL-3 R alpha/CD123 Protein
Product Source :
Recombinant Human IL-3 R alpha/CD123 Protein is expressed from HEK293 with hFc tag at the C-Terminus. It contains Thr19-Arg305.[Accession | P26951-1]
Molecular Weight :
The protein has a predicted MW of 59.7 kDa. Due to glycosylation, the protein migrates to 70-80 kDa based on Tris-Bis PAGE result.
Endotoxin Level :
Less than 1EU per μg by the LAL method.
Purity :
> 90% as determined by Tris-Bis PAGE> 90% as determined by HPLC
Formulation :
Lyophilized from 0.22μm filtered solution in 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 IL-3 R alpha on Tris-Bis PAGE under reduced condition. The purity is greater than 90%. SEC-HPLC The purity of Human IL-3 R alpha is greater than 90% as determined by SEC-HPLC. ELISA Data Immobilized Human IL-3, His Tag at 5μg/ml (100μl/well) on the plate. Dose response curve for Human IL-3 R alpha, hFc Tag with the EC50 of 0.46μg/ml determined by ELISA.
Background :
Interleukin-3 receptor subunit alpha, also known as IL-3 receptor subunit alpha, IL-3R-alpha, CD123, and IL3RA, is a single-pass type I membrane protein which belongs to the type I cytokine receptor family and Type 5 subfamily.The specific alpha subunit of the interleukin-3 receptor (IL-3Ralpha, CD123) is strongly expressed in various leukemic blasts and leukemic stem cells and seems to be an excellent target for the therapy of leukemias.
Synonyms :
CD123; IL-3R subunit alpha; IL3R; IL3RA; IL-3Ra; IL3RAY; IL3RX; IL3RY; MGC34174; IL-3 R alpha
