IL-4 is 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 allergic response. 别名: Interleukin-4; IL-4; B-Cell Stimulatory Factor 1; BSF-1; Binetrakin; Lymphocyte Stimulatory Factor 1; Pitrakinra; IL4 Accession: P05112 纯度: Greater than 95% as determined by reducing SDS-PAGE. 来源: Human Cells 内毒素水平: Less than 0.1 ng/ug (1 EU/ug) as determined by LAL test. 活性: Measured in a cell proliferation assay using TF-1 human erythroleukemic cells The ED50 for this effect is typically 0.08-0.2 ng/ml 溶解方法: Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. 形态: Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH 7.4. 储存/保存方法: Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7°C for 2-7 days.Aliquots of reconstituted samples are stable at < -20°C for 3 months. 产品信息订购:
