Source / Purification

Recombinant mouse His6IL-6 (mHis6IL-6) Phe25-Thr211 (Accession #NP_112445) was expressed in human 293 cells at Cell Signaling Technology.

CST公司利用重组的鼠His6IL-6 (mHis6IL-6) Phe25-Thr211 (Accession #NP_112445)在人的293细胞中表达。

Molecular Characterization

Recombinant N-terminally His6-tagged mIL-6 has a calculated MW of 24,311. DTT-reduced and non-reduced protein migrate as 31-36 kDa polypeptides. Lower mobility and heterogeneity in SDS-PAGE are due to glycosylation. The expected amino terminus of recombinant mHis6IL-6 was verified by amino acid sequencing.

重组的mIL-6蛋白在N-末端有His6标签,其分子量据推算为24,311Da。DTT-还原 和 未还原的蛋白迁移时是作为一个31-36kDa 的多肽而转移。其在SDS-PAGE胶中的双重迁移性质与低迁移速率是由于糖基化。重组mHis6IL-6蛋白的N-末端序列通过测序得到。


>98% as determined by SDS-PAGE of 6 μg reduced (+) and non-reduced (-) recombinant mHis6IL-6. All lots are greater than 98% pure.

6 μg 还原 (+) 和 非还原的(-) mHis6IL-6通过SDS-PAGE检测,纯度大于98%,所有批次的纯度均高于98%。


The bioactivity of recombinant mIL-6 was determined in a B9 cell proliferation assay. The ED50 of each lot is between 0.5 and 5 pg/ml.重组蛋白mIL-6的生物活性是通过B9细胞增殖实验确定的。每个lot的ED50在0.5-5 pg/ml之间。

IL-6 is a potent inducer of the acute phase response and is produced by T cells, macrophages, fibroblasts, endothelial, and other cells (1,2). IL-6 induces proliferation and differentiation and acts on B cells, T cells, thymocytes, among others. IL-6 in concert with TGF-β is important for developing Th17 responses. IL-6 binds to IL-6Rα and through this association induces gp130 homodimerization (1). gp130 homodimerization triggers the Jak/Stat cascade and the SHP2/MAPK (Erk) cascade (1,3,4). IL-6 also forms a complex with an IL-6Rα splice variant that is non-membrane associated (3). This IL-6/soluble IL-6Rα complex can activate the gp130 signaling pathway on cells that express gp130, but not IL-6Rα (3). Research studies have shown that IL-6 may contribute to metastatic breast cancer by increasing expression of proangiogenic VEGF (5).

IL-6是一个潜在的急性期应答的诱导因子,它由T细胞、巨噬细胞、纤维原细胞、内皮细胞和其它细胞产生(1,2)。IL-6诱导细胞增殖和分化并作用于B细胞、T细胞、胸腺细胞和其它细胞之中。IL-6与TGF-β相作用,对Th17应答的发展非常重要。IL-6与IL-6Rα结合并通过此结合诱导gp130的同型二聚化(1)。gp130的同型二聚化引起Jak/Stat级联反应和SHP2/MAPK (Erk)级联反应(1,3,4)。IL-6也能与IL-6Rα可变剪切形成与膜无关的复合体(3)。IL-6/可溶性 IL-6Rα 复合体在表达gp130的细胞上能激活gp130信号通路,但不是IL-6Rα (3)。一些研究证明IL-6可能通过增加促血管新生因子 VEGF对乳腺癌的转移有作用(5)。
