Recombinant Human IL7R protein (Met1-Gly236, I66T, V138I), His-tagged

Specification :
| Source : HEK293 | Species : Human | Tag : C-His | Protein length : Met1-Gly236, I66T, V138I | Form : Lyophilized from sterile PBS, pH 7.4 | Bio-activity : Measured by its ability to bind biotinylated mouse TSLP-his in functional ELISA. | Molecular Mass : The recombinant human IL7Rαconsists of 227 amino acids and has a predicted molecular mass of 26.3 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of human IL7Rα is approximately 44 kDa due to glycosylation. | Endotoxin : | Purity : ≥ 92 % as determined by SDS-PAGE. ≥ 95 % as determined by SEC-HPLC. | Storage : Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. | Reconstitution : It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
