【Abstract】 Objective: To optimize and establish two-dimensional electrophoresis(2-DE) steps for proteome analysis of retinal pigment epithelium(RPE) cells.Methods: Total soluble proteins of ARPE-19 cells were extracted,then experimental conditions were changed to find out the best one for RPE.Results: There were 300±10 spots apparently displayed,and differential expressing proteins can be found out after image analyzing of 2-DE gels between the experiment group and the normal control group.Conclusion: These 2-DE steps meet the qualifications for research in RPE cells proteome and are useful to further study on differential proteome profiles.更多还原
