gp130/IL6ST 蛋白, Rat (HEK293, His)

Glycoprotein 130 (gp130) is a trans-membrane protein, is the common signal-transducing receptor subunit of the interleukin-6 (IL-6) family^[1]. gp130 inhibits the cell growth and migration^[3], decreases the STAT3 phosphorylation induced by IL-6, and decreases IL-6-induced increase of Ki67. gp130 shows anti-tumor, anti-inflammation and anti-nociceptive activity^[4][5]. gp130/IL6ST Protein, Rat (HEK293, His) is a recombinant protein with a His label that consists of 614 amino acids (M4-E618) and is produced by HEK293 cells.

糖蛋白130 mRNA在人体内广泛表达，在隐静脉、心包、卵巢、网膜脂肪组织、腹膜、脾淋巴结和三叉神经节中表达水平最高。与胎儿器官相比，成人器官中gp130的表达显着增加。此外，与正常组织相比，gp130 在多种类型的癌症中高表达^[3]。
人 gp130 蛋白的氨基酸序列与小鼠和大鼠 gp130 蛋白的同源性较低。
当自分泌或旁分泌细胞因子诱导 gp130 和 α 受体亚基二聚化形成受体复合物时，gp130 信号传导启动，导致下游信号级联的激活，例如 JAK/STAT、PI3K/Akt、和 Ras/Raf/Mek/Erk1/2MAPK 通路。JAK/Stat3通路的激活诱导其靶基因表达，导致细胞生长、增殖（cyclin D、CDC25 A、c-Myc、survivin）、生存（survivin、Bcl-2、Bcl-X_L)、血管生成 (VEGF) 和细胞迁移（MMP-2、MMP-7 和 MMP-9）^[3]。gp130 是一种 IL-6 拮抗剂，具有抗肿瘤、抗炎和抗伤害活性^[4]。gp130 降低 IL-6 诱导的 STAT3 磷酸化，并降低 IL-6 诱导的 Ki67^[5] 增加。

Immobilized Human gp130, His Tag at 5 μg/mL (100 μL/well) can bind Biotinylated Human IL-6 R alpha that produces 50% of the optimal binding response is found to be approximately 4.94 ng/mL.

90-100 kDa.

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

无菌粉末

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4 or 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.
