- 状态
- Lyophilized
- 溶解方式
- The lyophilized IL-4 should be reconstituted in water to a concentration not less than 100 μg/mL. This solution can be diluted into other buffered solutions or stored at -20 °C for future use.
- 缓冲液
- PBS
- 注意事项
- Avoid repeated freeze-thaw cycles.
- 储存条件
- RT,0 °C,4 °C,-20 °C
- 储存方法
- The lyophilized IL-4, though stable at room temperature, is best stored desiccated below 0°C. Reconstituted IL-4 should be stored in working aliquots at -20°C. Avoid repeated freeze-thaw cycles.

- 背景
-
IL-4 is a pleiotropic cytokine that regulates diverse T and B cell responses including cell proliferation, survival and gene expression. 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 130 amino acid residues
