Two-dimensional gel electrophoresis for the identification of signaling targets. Journal Article uri icon



  • Two-dimensional electrophoresis (2-DE) is a powerful technique to differentially display patterns of protein expression and posttranslational modifications, providing a good strategy to monitor molecular responses induced by the activation or inactivation of specific signaling pathways. In this chapter, optimized protocols for 2-DE using extracts from tissue culture are provided. Protocols for in-gel digestion of gel-resolved proteins, which allow protein identification by mass spectrometry are also discussed.
