Source / Purification
Recombinant mouse interleukin-3 (mIL-3) Ala27-Cys166 (Accession # NM_010556) was produced in E. coli at Cell Signaling Technology.
CST公司生产的鼠源重组蛋白白介素-3 (mIL-3) Ala27-Cys166 (Accession # NM_010556)是从大肠杆菌中表达而来。
Recombinant mIL-3 does not have a Met on the amino terminus and has a calculated MW of 15,674. DTT-reduced protein migrates as a 16 kDa polypeptide and non-reduced protein migrates as a 14 kDa polypeptide due to intramolecular cystines. The expected amino-terminal ASISG of recombinant mIL-3 was verified by amino acid sequencing.
>98% as determined by SDS-PAGE of 6 μg reduced (+) and non-reduced (-) recombinant mIL-3. All lots are greater than 98% pure.
6 μg 还原 (+) 和 非还原的(-) mIL-3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-3 was determined in MC/9 and BaF3 cell proliferation assays. The ED50 of each lot is between 2-50 pg/ml in MC/9 cells and 20-90 pg/mL in BaF3 cells.
The purity of recombinant mIL-3 was determined by SDS-PAGE of 6 µg reduced (+) and non-reduced (-) recombinant mIL-3 and staining overnight with Coomassie Blue.重组mIL-3 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-3蛋白跑SDS胶并用考马斯亮蓝染色过夜。
The proliferation of MC/9 cells treated with increasing concentrations of mIL-3 was assessed. After 72 hour treatment with mIL-3, cells were incubated with a tetrazolium salt and the OD450 - OD650 was determined.在mIL-3蛋白浓度递增条件下研究MC/9细胞增殖实验。用mIL-3培养细胞72小时后用四唑盐处理。并测定OD450 - OD650值。
The proliferation of BaF3 cells treated with increasing concentrations of mIL-3 was assessed. After 48 hour treatment with mIL-3, cells were incubated with a tetrazolium salt and the OD450 - OD650 was determined.在mIL-3蛋白浓度递增条件下研究BaF3细胞增殖实验。用mIL-3培养细胞48小时后用四唑盐处理。并测定OD450 - OD650值。
Western blot analysis of extracts from BaF3 cells, untreated or treated with mIL-3 for 10 minutes, using Phospho-Stat5 (Tyr694) (C11C5) Rabbit mAb #9359 (upper) and Stat5 (3H7) Rabbit mAb #9358 (lower).Western免疫印迹。用Phospho-Stat5 (Tyr694) (C11C5) Rabbit mAb #9359 (上图) 和 Stat5 (3H7) Rabbit mAb #9358 (下图) 研究未经处理的和经mIL-3处理10 min的 BaF3 细胞的细胞提取液。

IL-3 is produced by T cells, mast cells and eosinophils (1). Target cells include hematopoietic progenitors, neutrophils, macrophages, mast cells, eosinophils, lymphoid and erythroid cells (1). IL-3 supports growth and differentiation and is used as a media additive to support culture of many cell types (1). The IL-3 receptor is a heterodimer of the IL-3 specific α-chain and the common β-chain, βc, which is also used by GM-CSF and IL-5. (1). Binding of IL-3 can also involve substitution of the βc by a βIL-3-chain that appears to be specific for IL-3 (1,2). Binding of IL-3 to its cognate receptor(s) induces activation of Jak2, phosphorylation of multiple Stats (1,3,5,6), and the PI3K/Akt pathway (1). IL-3 may play an important role in the development of airway inflammation associated with asthma (3,4,5).
IL-3是通过T细胞、肌肉细胞和噬曙红细胞而产生的(1)。目标细胞包括造血原细胞、嗜中性粒细胞、巨噬细胞、肌肉细胞、噬曙红细胞、淋巴细胞和色调微红细胞(1)。IL-3支持生长和分化并且作为很多类型细胞的培养基的添加成分(1)。IL-3受体是一个异源二聚体包含IL-3 特异的α-链和普遍存在的β-链, βc, 也被GM-CSF 和 IL-5所利用 (1)。IL-3特异性的βIL-3-链可替换βc并参与到IL-3的结合中 (1,2)。IL-3结合到其同类的受体上诱导了Jak2的激活,磷酸化多个Stats (1,3,5,6), 和 PI3K/Akt信号通路(1)。IL-3在气管炎症引发的哮喘过程中有重要的作用(3,4,5)。
