This is a standard technique: Separate by one- or twodimensional electrophoresis, western-blot onto PVDF membranes, stain with Coomassie blue or Ponceau red, cut out the interesting bands and put them (still on the PVDF) into a gas phase sequencer. You have to use PVDF membranes though, nitrocellulose does not work. .
