5. Proteomics application fields

The combined use of separative techniques (electrophoresis and mono- or multi-dimensional chromatography), analytical techniques (mass spectrometry and tandem mass spectrometry) and bioinformatics tools (nucleotide and protein database interrogation interfaces), provides invaluable protein information for understanding cellular mechanisms or identifying the proteins involved. The constant development of analytical tools such as separative media and the implementation of new analysis methodologies
