分子别名（Synonym）:CD122,IL15RB,P70-75

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 recombinant human IL2 Rβ/Fc is a disulfide-linked homodimeric protein generated after removal of the signal peptide. The reduced monomer consists of 451 amino acids and has a predicted molecular mass of 51.6 kDa. As a result of glycosylation, the apparent molecular mass of rh IL2RB/Fc monomer is approximately 60-65 kDa in SDS-PAGE under reducing conditions.

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 biotinylated recombinant rat IL2 in a functional ELISA.

表达区间（Protein Construction）：A DNA sequence encoding the extracellular domain (Ser 2-Asp 239) of human IL2 Rβ (NP_000869.1) precursor was expressed with the C-terminal fused Fc region of human IgG1.

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.
