Proteomics: an analytical challenge
There are no PCR-like techniques for proteins.
Proteomics is more complex than transcriptomics.
Protein levels are very different.
## What? Highly precise determination of molecular masses of molecules and its aggregates.
Produces gas-phase ions of the molecules. Determines the mass/charge ratio of these ions through their interaction with electric, magnetic or RF fields.
A mass spectrometer is a precision balance (scale) for molecules.
