| Abstract: | As part of our continuing studies into the biochemical basis of long-term changes in neuronal function in Aplysia, we have developed a simple method for obtaining amino acid sequence information from proteins isolated on two-dimensional gels. Proteins isolated on preparative two-dimensional gels are digested in situ with Staphylococcus aureus V8 protease, and the resulting peptides electrophoresed, transferred to a polyvinylidene difluoride membrane, and sequenced in a gas-phase sequencer. The method is simple and should be applicable to a variety of other systems where the development of a two-dimensional gel database is underway. |
