Primary DP cells and iDP6 cells were cultured. The iDP6 cells were treated with AdGFP (adenovirus with the ability to express GFP protein), AdFlip (adenovirus with the ability to express flip recombinase, which can interact with FRT thus remove the expression of SV40) or PBS. Forty-eight hours later, cells were collected and total proteins were extracted with RIPA lysis buffer (Beyotime, Shanghai, China). Then, total proteins were loaded to 1% SDS-PAGE gel (Beyotime, China) and transmitted to PVDF membrane (Bio-Rad, Hercules, CA, USA). The PVDF membrane were incubated with anti-SV40 (1:1,000; Santa Cruz Biotechnology, Dallas, TX, USA) and anti-GAPDH (1:500; ZSGB-bio, Beijing, China) antibodies. HRP labelled secondary antibodies were used, and the results were observed under ChemiDoc™ Touch Imaging System (Bio-Rad, Hercules, CA, USA).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
