The Current and Future State of Top-Down Protein Sequencing by ESI-Tandem Mass Spectrometry

In this column, we introduce the basics of today’s approaches for doing intact protein dissociation with mass spectrometry (MS), or top-down sequencing (that is, rather than the more conventional peptide-based “bottom-up” sequencing where future improvements might occur, advantages and limitations of using top-down sequencing, possible applications, and why it has become such an important and pursued research area for many.
