Abstract:Proteomics is a new subject for large-scale analysis of gene coding protein. This paper describes the basic technology of proteomics: application two-dimensional gel electrophoresis, multidimensional liquid chromatography, mass spectrometry, protein chip and their application in type 2 diabetes, to explore the biological protein related to inflammation and dyslipidemia in type 2 diabetes, such as C reaction protein, alpha macroglobulin, apolipoprotein 2-A1, Clusterin protein and zinc alpha-2 glycoprotein, and to find some new mellitus specific markers and drug targets for early diagnosis of type 2 diabetes.
