Human CD122 / IL-2RB Protein

分子别名（Synonym）:CD122,IL15RB,P70-75 种属（Species）：Human 表达系统（Expressed Host）：HEK293 Cells 制剂（Buffer）：Lyophilized from sterile 100mM NaCl, 50mM Tris, pH 7.5 分子量（Molecule Mass）：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. 内毒素（Endotoxin）：＜1.0 EU per μg by the LAL method. 生物活性(Activity)：1. Measured by its binding ability in a functional ELISA. 表达区间（Protein Construction）：The mature form of human IL2 Rβ (NP_000869.1) extracellular domain (Ser 2-Asp 239) with five amino acids (DDDDK) at the C-terminus was expressed and purified. 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.
