Recombinant Human IL-2 (E. coli) 别名：Interleukin-2; T-Cell Growth Factor; TCGF; 重组人IL-2 (E. coli)
Interleukin-2(IL-2) is a type of cytokine signaling molecule in the immune system. IL-2 stimulates growth and differentiation of B-cells, NK cells, lymphokine-activated killer cells, monocytes, macrophages and oligodendrocytes. It is a powerful immunoregulatory lymphokine produced by T-cells in response to antigenic or mitogenic stimulation.

生物活性
Interleukin-2(IL-2) is a type of cytokine signaling molecule in the immune system. IL-2 stimulates growth and differentiation of B-cells, NK cells, lymphokine-activated killer cells, monocytes, macrophages and oligodendrocytes. It is a powerful immunoregulatory lymphokine produced by T-cells in response to antigenic or mitogenic stimulation.
Recombinant Human IL-2 expressed the target gene encoding Ala21-Thr153.
Measured by a cell proliferation assay using CTLL-2 mouse cytotoxic T cells, the specific activity is ≥1×107 IU/mg.

实验参考
建议您制定动物给药及实验方案时，尽量参考已发表的相关实验文献（溶剂种类及配比众多，简单地溶解目的化合物，并不能解决动物给药依从性、体内生物利用度、组织分布等相关问题，未必能保证目的化合物在动物体内充分发挥生物学效用）。
体内实验的工作液，建议您现用现配，当天使用；如在配制过程中出现沉淀、析出现象，可以通过超声和（或）加热的方式助溶。
切勿一次性将产品全部溶解。
请在下面的计算器中，输入您的动物实验相关数据并点击计算，即可得到该实验的总需药量和工作液终浓度。
例如您给药剂量是10 mg/kg，平均每只动物的体重为20 g，每只动物的给药体积是100 μL，动物数量为20只，则该动物实验的总需药量为4 mg，工作液终浓度为2 mg/mL。
1：鉴于实验过程的损耗，建议您至少多配1-2只动物的量；
2：为该产品最终给药时的浓度。
