Cells of 0.2 million were seeded in chamber (154526, Thermo Scientific), and cultured for two days. Cells were fixed with cold methanol, membrane perforated with 0.15% Triton X-100 (TB0198, Sangon Biotech), blocked with animal non-immune serum (SP KIT-B, Maxvision), and incubated with primary antibodies overnight at 4℃, and then incubated with secondary antibodies for one hour. Cell nucleus was stained with DAPI (P36931, Life Technologies). Images were captured with confocal microscope (LSM 710, Zeiss) with 100x oil objective lens.

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.
