Objective:To establish and optimize the two-dimensional gel electrophoresis(2-DE)and the preparation of protein samples for the proteome of HeLa cells.Methods:The proteins of HeLa cell were extracted by three different lysis buffers to do 2-DE.The gel images then were acquired by Amersham ImageMaster VDS-CL to do the comparative analysis with PDQuest(7.4.0)software.Results:The combination of Thiourea and Urea can be favorable for the extraction of proteins
and increase the amount of the detectable spots for the alkaline protein.The application of broad-spectrum protease inhibitor could increase the amount of the detectable protein spots in 2-DE remarkably
and also the alkaline protein spots.Conclusions:A two-dimensional electrophoresis technique for HeLa cells was established and an ideal 2-DE map with higher resolution and better reproducibility for HeLa cells was obtained clearly
which laid a foundation for the further studies on proteome of HeLa cells.
