Proteomics and automation

Abstract

Proteome analysis is concerned with the global changes in protein expression as visualized most commonly by two‐dimensional gel electrophoresis and analyzed by mass spectrometry. A drastic increase in the rapidity and reproducibility of protein isolation and identification is needed for proteome analysis to become a useful complement to global mRNA analysis. Simplification and standardization, based on innovation in both hard‐ and software, are prerequisites to the creation of automated proteomics platforms that are both robust and user‐friendly, and will allow many more laboratories access to this technique. In this review we highlight the weak points in the chain of analysis (such as sample handling, protein separation and digestion) and summarize recent trends toward automation in instrumentation and software and offer our own personal view of future developments in the field.
