||Recombinant Human IL2RB mature form extracellular domain (Met 1-Asp 239) (NP_000869.1), fused with five amino acids (DDDDK) at the C-terminus, was produced in Human Cell.
||Lyophilized from sterile 100mM NaCl, 50mM Tris, pH 7.5
||The mature recombinant human IL2 Rβ consists of 219 amino acids and has a predicted molecular mass of 25.2 kDa. As a result of glycosylation, the rh IL2 Rβ migrates as an approximately 40 kDa protein in SDS-PAGE under reducing conditions.
||< 1.0 eu per μg of the protein as determined by the LAL method.
||Samples are stable for up to twelve months from date of receipt at -70oC.
||Store it under sterile conditions at -20oC~-70oC. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
||It is recommended that sterile water be added to the vial to prepare a stock solution. Centrifuge the vial at 4oC before opening to recover the entire contents.
