分子别名（Synonym）:CD25,IDDM10,IL-2RA,IL2R,p55,TCGFR

种属（Species）：Human

表达系统（Expressed Host）：HEK293 Cells

产品状态（Buffer）：Lyophilized from sterile PBS, pH 7.4

分子量（Molecule Mass）：The mature recombinant human IL2Rα/Fc is a disulfide-linked homodimeric protein generated by proteolytic removal of the signal peptide. The reduced monomer consists of 430 amino acids and has a predicted molecular mass of 48.5 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rhIL2Rα/Fc monomer is approximately 72 kDa due to glycosylation.

内毒素（Endotoxin）：＜1.0 EU per μg by the LAL method.

生物活性(Activity)：1. Measured by its ability to bind recombinant rat IL2 (Cat:R1299-NAE) in a functional ELISA.

表达区间（Protein Construction）：A DNA sequence encoding the amino acid residues (Ser 2-Cys 213) of the human IL2 receptor α chain (NP_000408.1) precursor was expressed with C-terminal fused human IgG1 Fc region.

存储条件（Storage）： For long term storage, the product should be stored at lyophilized state at -20℃ or lower.Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at:4-8℃ for 12 months in lyophilized state;-70℃ for 3 months under sterile conditions after reconstitution.

运输条件： In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
