Produced by mast cells, T cells ａnd bone marrow stromal cells, IL-4 regulates the differentiation of naive CD4+ T cells into helper Th2 cells, characterized by their cytokine-secretion profile that includes secretion of IL-4, IL-5, IL-6, IL-10, ａnd IL-13, which favor a humoral immune response. Another dominant function of IL-4 is the regulation of immunoglobulin class switching to the IgG1 ａnd IgE isotypes. Excessive IL-4 production by Th2 cells has been associated with elevated IgE production ａnd allergy. Recombinant human IL-4 is a 14.9 kDa globular protein containing 129 amino acid residues. 氨基酸序列: MHKCDITLQE IIKTLNSLTE QKTLCTELTV TDIFAASKNT TEKETFCRAA TVLRQFYSHH EKDTRCLGAT AQQFHRHKQL IRFLKRLDRN LWGLAGLNSC PVKEANQSTL ENFLERLKTI MREKYSKCSS 来源: E.coli 纯度: Greater than 98% by SDS-PAGE gel ａnd HPLC analyses. 生物活性: The ED₅₀ as determined by the dose-dependent stimulation of human TF-1 cells is ≤ 0.2 ng/ml, corresponding to a specific activity of ≥ 5 x 10⁶ units/mg. 研究领域: 细胞凋亡癌症 细胞培养免疫系统 炎症增殖 干细胞及分化过敏 移植 原产国: USA 仅用于研究。不适用于诊断或ZL。
