How does mass spectrometry work in proteomics?
Mass spectrometers do one thing—they measure mass.
In proteomics, the mass gives information on the protein identity, its chemical modifications, and its structure.
Every mass spectrometer has three main components: a source, an analyzer, and a detector..

What are computational methods in proteomics?
Computational Proteomics is about the computational methods, algorithms, databases and methodologies used to process, manage, analyze and interpret the data produced in proteomics experiments..
What are the methods used to study proteomics?
Several high-throughput technologies have been developed to investigate proteomes in depth.
The most commonly applied are mass spectrometry (MS)-based techniques such as Tandem-MS and gel-based techniques such as differential in-gel electrophoresis (DIGE)..

MassQC.- Introduction to Computational Proteomics introduces the field of computational biology through a focused approach that tackles the different steps and problems involved with protein analysis, classification, and meta-organization.
- Mass spectrometry (MS) is a commonly used, high-throughput tool for studying proteins.
The procedure of MS-based protein identification involves digesting proteins into peptides, which are then separated, fragmented, ionised, and captured by mass spectrometers. - Relative quantification methods include isotope-coded affinity tags (ICAT), isobaric labeling (tandem mass tags (TMT) and isobaric tags for relative and absolute quantification (iTRAQ)), label-free quantification metal-coded tags (MeCAT), N-terminal labelling, stable isotope labeling with amino acids in cell culture (
