WebbThe dried peptides should be invisible (no powder). Prewash 500 µl Eppendorf tubes with 500 µl 0.1% FA/60% CH3CN. Put the Coomassie Blue-stained gel band into one prewashed tube. Also excise a blank section of the gel that should not contain protein and place it in a prewashed 500 µl tube. Add250 µl 50% H2O/50% acetonitrile and wash for … WebbCut the gel as close to the band as possible to reduce the volume of gel to be processed. Cut into 4-5 pieces and place into a 500 μL microcentrifuge tube. Push gel pieces down …
