Oncostatin M(OSM,抑瘤素M)作为白介素6家族细胞因子的成员,在炎症、自身免疫和癌症中起着重要作用。OSM最初被引入为抗癌剂。但在某些情况下,它会促进癌症发展,OSM可能在增强癌细胞的生长,侵袭,存活等方面起到重要作用。此外,OSM还可能与难治性炎症性肠病(IBD)有关。Oncostatin M全长209个氨基酸。

Oncostatin M (OSM) is a multifunctional cytokine, and belongs to Interleukin-6 (IL-6) subfamily, which also includes IL-11, leukemia inhibitory factor (LIF), ciliary neurotropic factor, cardiotrophin-1, and novel neurotropin-1.
Human OSM can bind to gp130 and recruit OSM Receptor β or LIF Receptor β to form a ternary complex. OSM stimulates the growth of different types of cells, including megakaryocytes, fibroblasts, vascular endothelial cells, and T cells. OSM inhibits the proliferation of several cancer cell lines, such as solid tissue tumor cells, lung cancer cells, melanoma cells, and breast cancer cells.

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。
