Recombinant mouse IL-1β (mIL-1β) Val118-Ser269 (Accession #NP_032387) was produced in E.coli at Cell Signaling Technology.
CST公司生产的鼠源重组蛋白IL-1β (mIL-1β) Val118-Ser269 (Accession #NP_032387)是从大肠杆菌细胞表达而来。
Recombinant mIL-1β has a Met on the amino terminus and has a calculated MW of 17,525. DTT-reduced and non-reduced protein migrate as 18 kDa polypeptides. The expected amino-terminal MVPIR of recombinant mIL-1β was verified by amino acid sequencing.
重组的 mIL-1β 蛋白在N-末端有Met标签，其蛋白分子量据推算为17,525Da。DTT-还原和未还原的蛋白作为一个18kDa的蛋白转移。重组mIL-1β蛋白的N-末端MVPIR的序列通过测序得到。
>98% as determined by SDS-PAGE of 6 μg reduced (+) and non-reduced (-) recombinant mIL-1β. All lots are greater than 98% pure.
6 μg 还原 (+) 和 非还原的(-) mIL-1β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-1β was determined by its ability to induce mouse IL-6 production by 3T3 MEFs WT. The ED50 of each lot is between 5-20 pg/ml.
重组的mIL-1β生物活性是通过诱导3T3 MEFs WT细胞产生IL-6的能力来确定的。每个批次的ED50在5-20 pg/ml之间。
The purity of recombinant mIL-1β was determined by SDS-PAGE of 6 µg reduced (+) and non-reduced (-) recombinant mIL-1β and staining overnight with Coomassie Blue.重组mIL-1β 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mIL-1β 蛋白跑SDS胶并用考马斯亮蓝染色过夜。
Western blot analysis of extracts from 3T3 MEFs WT untreated or treated with mIL-1β for 15 minutes, using Phospho-NF-κB p65 (Ser536) (93H1) Rabbit mAb #3033 (upper) and NF-κB p65 (E498) Antibody #3987 (lower).Western免疫印迹。用Phospho-NF-κB p65 (Ser536) (93H1) Rabbit mAb #3033 (上图)和NF-κB p65 (E498) Antibody #3987 (下图) 研究未经处理和经mIL-1β 处理15min的3T3 MEFs WT 细胞的细胞提取液。
The production of mouse IL-6 by 3T3 MEFs WT cultured with increasing concentrations of mIL-1β was assessed. Media from cells incubated with mIL-1β for 24 hours was collected and assayed for mouse IL-6 by ELISA and the OD450-OD650 was determined.用浓度递增mIL-1β 蛋白培养3T3 MEFs WT 细胞并研究其产生IL-6能力实验。用mIL-1β 培养细胞24小时后取培养基经ELISA测定IL-6并测定OD450 - OD650值。

IL-1β is a pro-inflammatory cytokine produced predominantly by activated monocytes and epithelial cells (1). Precursor IL-1β is cleaved by caspase-1 and mature IL-1β is then secreted (1-3). Target cells include macrophages and many other cell types. Signaling by IL-1β involves IL-1β binding to IL-1 accessory protein (IL-1-AcP) and then the complex binds to IL-1RI (1,2). Signaling is through activation of MAP kinase and NF-κB pathways (1,2). IL-1β also binds to IL-1RII that lacks an intracellular signaling domain and thereby serves as a high affinity decoy receptor. IL-1β binding to IL-1RI is inhibited by the negative regulator, IL-1R antagonist (IL-1Ra). IL-1Ra binding to IL-1RI does not signal and serves to block IL-1β signaling. IL-1β plays critical roles in the acute phase response and sepsis (1-3).
IL-1β是促炎症因子，主要的由激活的单核细胞和上皮细胞产生(1)。IL-1β的前体被caspase-1剪切，成熟的IL-1β紧接着被分泌(1-3)。目标细胞包括巨噬细胞和许多其它的细胞类型。IL-1β引起的信号通路包括IL-1β结合到IL-1的附属蛋白 (IL-1-AcP); 此复合体紧接着结合到IL-1RI (1,2)。信号通过激活MAP激酶和 NF-κB信号通路(1,2)。IL-1β也结合到IL-1RII,它缺乏细胞内的信号区域并因此作为高亲和性的诱捕受体。IL-1β结合到IL-1RI的过程能够被负调控因子IL-1R拮抗剂IL-1Ra所抑制。IL-1Ra结合到IL-1RI后无信号传导并且作为抑制剂阻止IL-1β信号通路。IL-1β在急性应答期和脓毒病中发挥了重要的作用(1-3)。
