Objective:To establish proteomic technique system of human hepatocellular carcinoma cell line QCY-7701. Method:Two different lysis buffer were taken to extract cell proteins. After two-dimensional gel electrophuresis (2-DE) and PDQuest analysis
10 good-matched protein spots were chosen to be identified by MALDI-TOF-MS. Results:A steady 2-DE electrophregram of hepatocellular carcinoma cell line QGY-7701 was established. Compared with lysis bufferⅠ
protein quantities extracted from lysis bufferⅡincreased by 25%;protein spots in 2-DE gel increased by 32%. 9 out of 10 candidate protein spots were successfully identified (P<0.05). Conclusions:Our established proteomic technique of human hepatocellular carcinoma cell line OGY-7701 can be effectively applied in cumparative pruteomics of drugs.
