The field has since expanded to include not only protein expression profiling, but the analysis of posttranslational modifications and proteinprotein interactions. Other protein capture methods be used in place of arrays, including the yeast twohybrid system or the isolation of proteinsprotein complexes by affinity chromatography or other separation techniques..

Advances in instrumentation and methodologies have fueled an expansion of the scope of biological studies from simple biochemical analysis of single proteins to measurements of complex protein mixtures. The field has since expanded to include not only protein expression profiling, but the analysis of posttranslational modifications and proteinprotein interactions. The study of proteinprotein interactions has been revolutionized by the development of protein microarrays.

Initially, proteomics focused on the generation of protein maps using twodimensional polyacrylamide gel electrophoresis. Analagous to DNA microarrays, these biochips are printed with antibodies or proteins and probed with complex protein mixture. The intenisty or indentity of the resulting proteinprotein interactions be detected by fluorescence imaging or mass spectrometry. Other protein capture methods be used in place of arrays, including the yeast twohybrid system or the isolation of proteinsprotein complexes by affinity chromatography or other separation techniques.. variety of platforms are available to conduct protein expression studies and this site provides links to these resources.

Coupled with advances in bioinformatics, this approach to comprehensively describing biological systems will undoubtedly have major impact on our understanding of the phenotypes of both normal and diseased cells. Other protein capture methods be used in place of arrays, including the yeast twohybrid system or the isolation of proteinsprotein complexes by affinity chromatography or other separation techniques. The field has since expanded to include not only protein expression profiling, but the analysis of posttranslational modifications and proteinprotein interactions.

Other protein capture methods be used in place of arrays, including the yeast twohybrid system or the isolation of proteinsprotein complexes by affinity chromatography or other separation techniques.. Protein expression, or the quantitative measurement of the global levels of proteins, still be done with twodimensional gels, however, mass spectrometry has been incorporated to increase sensitivity, specificity and to provide results in highthroughput format. variety of platforms are available to conduct protein expression studies and this site provides links to these resources.
