Abstract excerpt
We have developed a strategy to characterize protein isoforms, resulting from single-point mutations and post-translational modifications. This strategy is based on polyacrylamide gel electrophoresis separation of protein isoforms, mass spectrometry (MS) and MSn analyses of intact proteins, and tandem MS analyses of proteolytic peptides. We extracted protein isoforms from polyacrylamide gels by passive elution...
