Efficient methods for profiling of the cell surface proteome are desirable to get a deeper insight in basic biological processes, to localise proteins and to uncover proteins differentially expressed in diseases. Here we present a strategy to target cell surface exposed proteins via fluorescence labelling using CyDye DIGE fluors. This method has been applied to human cell lines in vitro as well as to a complex biological system in vivo . It allows detection of fluorophore‐tagged cell surface proteins and visualisation of the accessible proteome within a single 2‐D gel, simplifying subsequent UV MALDI‐MS analysis.
