Background:
Tumor Necrosis Factor-alpha (TNF-α) is a multifunctional pro-inflammatory cytokine, mainly secreted by activated macrophages. It is implicated with a variety of biological procedures including systemic inflammation, cell proliferation, apoptosis, lipid metabolism, and coagulation. The pleiotropic attribute of TNF-α regulation is associated with its ability to trigger multiple signalling pathways through its receptors, TNFR1 (p55) and TNFR2 (p75).
TNF-α not only contributes to the immune response to bacterial, fungal, viral and parasitic invasions, but also functions in tissue remodeling, autoimmune-diseases and the necrosis of specific tumors. TNF-α hyper-expression in response to some bacterial components such as LPS can cause life threatening septic shock. Recombinant TNF-α, in combination with chemotherapy, has been applied for treatment of soft sarcomas, melanomas and other irresectable tumors. Anti-TNF-α therapy has been used for treatment of rheumatoid arthritis.
Applications:
ELISA:When clone B1E4 is used as detection antibody and clone CH8820 (Cat. No.: MO-C40003B) is used as capture antibody in an ELISA assay that uses WHO reference material, the detection limit of the ELISA can reach 2.4pg/mL TNF-α.

2.将构建完成的载体与慢病毒包装质粒混合,共转染靶细胞
3.收集病毒液
4.用病毒液感染靶细胞
5.用载体上带的抗生素进行筛选,如果没有,可以用无限稀释法
6.获得稳转株
然后你得确定，这个细胞株对于你得研究来说不可或缺，具有明确的代表性。
上面两个都没有问题的话，祝你顺利。
1.将外源基因插入慢病毒载体
2.将构建完成的载体与慢病毒包装质粒混合，共转染靶细胞
3.收集病毒液
4.用病毒液感染靶细胞
5.用载体上带的抗生素进行筛选，如果没有，可以用无限稀释法
6.获得稳转株
如果经费充足的话可以找公司包装病毒，如武汉的普健可以提供各种载体的构建及细胞株构建的技术服务。
由于质粒的不兼容性,拥有同种复制子的质粒不能在同一细胞内稳定共存,经过几代的复制,会质粒丢失,所以并不是任何两个或两个以上质粒都可以在同一细胞内稳定存在,但是可以同时进入.
稳定转染的细胞株，就是转染后质粒可以稳定整合到基因组上不会因细胞分裂而丢失。区别于质粒瞬时转染不能长时间保留质粒在细胞里。
