Specifications Source Recombinant Human IL-7R alpha/CD127 Protein is expressed from HEK293 with hFc tag at the C-terminal. It contains Glu21-Gly236.[uniprot | P16871-1] Molecular W eight The protein has a predicted MW of 51.6 kDa. Due to glycosylation, the protein migrates to 65-75 kDa based on Tris-Bis PAGE result. Endotoxin Less than 1EU per μg by the LAL method. Purity > 95% as determined by Tris-Bis PAGE and HPLC Activity ELISA Data: Immobilized Human IL-7 at 0.5μg/ml (100μl/Well) on the plate. Dose response curve for Human IL-7R alpha, hFc Tag with the EC50 of 55.1ng/ml determined by ELISA Formulation Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. Reconstitution Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. Storage The product should be stored at -25~-15℃ for 1 year from date of receipt. 2-7 days, 2 ~8 °C under sterile conditions after reconstitution. 3 months, -25~-15℃ under sterile conditions after reconstitution. Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.
