Source / Purification

Recombinant human IL-10 (hIL-10) Ser19 - Asn178 (Accession # NP_000563) was expressed in human 293 cells at Cell Signaling Technology.

CST公司生产的人重组蛋白IL-10 (hIL-10) Ser19 - Asn178 (Accession # NP_000563)是从人的293细胞表达而来。

Molecular Characterization

Recombinant hIL-10 contains no "tags" and has a calculated MW of 18,647. DTT-reduced protein migrates as an 18 kDa polypeptide and non-reduced protein migrates as a 16 kDa polypeptide due to intramolecular cystines. The expected amino-terminal SPGQG of recombinant hIL-10 was verified by amino acid sequencing.

重组的hIL-10 蛋白在N-末端没有Met标签,蛋白分子量据推算为18,647Da。DTT-还原蛋白作为18kDa的多肽转移,而未还原蛋白由于有内部分子胱氨酸存在作为16kDa的多肽转移。重组hIL-10 蛋白的N-末端SPGQG的序列通过测序得到。

Purity

>98% as determined by SDS-PAGE of 6 μg reduced (+) and non-reduced (-) recombinant hIL-10. All lots are greater than 98% pure.

Bioactivity

The bioactivity of recombinant hIL-10 was determined in a MC/9 cell proliferation assay. The ED50 of each lot is between 0.3-1.4 ng/ml.

hIL-10 的生物活性是通过MC/9细胞增殖实验来确定的。每个批次的ED50在 0.3-1.4 ng/ml之间。

Coomassie Gel

Coomassie Gel

The purity of recombinant hIL-10 was determined by SDS-PAGE of 6 µg reduced (+) and non-reduced (-) recombinant hIL-10 and staining overnight with Coomassie Blue.重组hIL-10蛋白的纯度通过SDS-PAGE 来确定。6 µg 经还原(+)和未经过还原(-) 的重组hIL-10蛋白跑SDS胶并用考马斯亮蓝染色过夜。

Bioactivity

Bioactivity

The proliferation of MC/9 cells treated with increasing concentrations of hIL-10 in the presence of 1 pg/ml mouse IL-4 #5208 was assessed. After 72 hours treatment with hIL-10, cells were incubated with a tetrazolium salt and the OD450-OD650 was determined.在10 pg/ml鼠源IL-4 #5208 存在下hIL-10 蛋白浓度递增条件下研究MC/9细胞增殖实验。用hIL-10培养细胞72小时后用四唑盐孵育。并测定OD450 - OD650值。

Background

IL-10 is an anti-inflammatory cytokine that is produced by T cells, NK cells and macrophages (1,2). IL-10 initiates signal transduction by binding to a cell surface receptor complex consisting of IL-10 RI and IL-10 RII (1). Binding of IL-10 leads to the activation of Jak1 and Tyk2, which phosphorylates Stat3 (1,3). The anti-inflammatory activity of IL-10 is due to its ability to block signaling through other cytokine receptors, notably IFNγ receptor, by upregulating expression of SOCS1 (1,3). In addition, IL-10 promotes T cell tolerance by inhibiting tyrosine phosphorylation of CD28 (4,5). IL-10 is an important negative regulator of the immune response, which allows for maintenance of pregnancy (1). In contrast, increased IL-10 levels contribute to persistent Leishmania major infections (6).

IL-10 是抗炎症的细胞因子,它由T细胞、NK细胞和巨噬细胞产生(1,2)。IL-10通过结合细胞表面受体复合体包括 IL-10 RI和 IL-10 RII而起始信号转导(1)。结合IL-10导致Jak1和Tyk2的激活, 继而磷酸化Stat-3 (1,3)。IL-10的抗炎活性是由于它能通过其他的细胞因子受体而阻止细胞传递,特别是通过上调SOCS-1的表达而抑制IFNγ受体(1,3)。除此之外, IL-10通过抑制酪氨酸磷酸化CD28而促进T细胞耐受性(4,5)。IL-10是免疫应答的重要负调控因子,这能够维持怀孕状态(1)。相反,增加IL-10水平对利什曼虫的持续感染有很大的帮助(6)。
