1. Wash adherent cells twice in the dish or flask with ice-cold PBS and drain off PBS.
2. Add ice-cold modified RIPA buffer to cells (1 ml per 107 cells/100 mm dish; 0.5 ml per 5 x 106 cells/60 mm dish).
3. Scrape adherent cells off the dish or flask with either a rubber policeman or a plastic cell scraper that has been cooled in ice-cold distilled water. Transfer the cell suspension into pre-chilled Eppendorf microcentrifuge tubes. put it on ice for 20 minutes to lyse cells.
4. After vortex-mixing, centrifuging at 12,000 rpm for 10 min. at 4 ° C. Remove the supernatant and quantitate using a BCA Protein assay .作者: 49888 时间: 2014-1-19 13:04
