IL-2R gamma/CD132 蛋白, Human (HEK293, His)

IL-2R gamma (CD132), a type I cytokine receptor expressed on leucocyte subsets, is a receptor for IL-2. IL-2R gamma forms heterodimer with IL-2R beta, and increases the affinity of IL-2R beta for IL-2^[1]. IL-2R gamma plays an important role in the development, activation, proliferation, differentiation and regulation of lymphocytes and other cell types^[2]. IL-2R gamma/CD132 Protein, Human (HEK293, His) is a recombinant human extracellular region of IL-2R gamma (L23-A262) with a C-Terminal 6*His tag, which is produced in HEK293 cells.

IL-2R gamma (CD132) 是 IL-2 的一种受体，是 I 型细胞因子受体家族和 5 型亚家族的成员。IL-2R gamma 在白细胞亚群和人类单核细胞中表达^[1][3]。人 IL-2R γ 由胞外结构域 (L23-A262)、螺旋结构域 (V263-L283) 和胞质结构域 (E284-T369) 组成。
不同物种的IL-2Rβ的氨基酸序列不同。人 IL-2R gamma 与小鼠和大鼠的氨基酸序列同一性<75%。
IL-2R γ 对 IL-2 的亲和力较低，但与 IL-2R β 形成异二聚体时，对 IL-2 具有中等亲和力。当 IL-2 浓度相对较高时，IL-2R β/γ 异二聚体复合物会转导信号^[1]。IL-2Rγ可被IL-2、IL-4、IL-7、IL-9、IL-15受体利用，参与淋巴细胞及其他细胞的发育、活化、增殖、分化和调节。类型^[2]。IL-2R gamma 受到 IL-2 和 IFN gamma^[3] 的严格上调。L-2R gamm 突变会导致人类 X 连锁严重联合免疫缺陷 (XSCID)^[4]。
IL-2R gamma 参与炎症反应，并介导细胞活化^[1]。

IL-2R gamma (human) migrates with a molecular weight corresponding to 55–60 kDa (immunoblotting of lysates prepared from Sf9 cells infected with VL1392-hIL-2Rγ)^[5].
IL-2R gamma binds to IL-2 in recombinant IL-2R gamma plasmid (pGEX-4T-1-IL-2Rγ)-transfected 293T cells^[6].

Greater than 95% as determined by reducing SDS-PAGE.

无菌粉末.

Lyophilized from a 0.2 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.4.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US;may vary elsewhere.
