Recombinant Human IL15RA protein(Ile31-Thr205), His-tagged

Specification :
| Source : E. coli | Species : Human | Tag : N-His | Protein length : Ile31-Thr205 | Form : Lyophilized from sterile 20mM Tris, 1mM DTT, 100mM NaCl, pH 8.0. Normally 5 % – 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. | Molecular Mass : The recombinant human IL15RA consists of 190 amino acids and predicts a molecular mass of 20.22 KDa. | Endotoxin : | Purity : > 95 % as determined by SDS-PAGE. | 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.
