How is mass spec used 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 Psms in proteomics?

A peptide-spectrum match (PSM) scoring function assigns a numerical value to a peptide-spectrum pair (P,S) expressing the likelihood that the fragmentation of a peptide with sequence P is recorded in the experimental mass spectrum S.

What is a proteomics platform?

The Proteomics Platform provides best-in-class mass spectrometry-based proteomic technologies and analysis capabilities to the Broad community and collaborators throughout the United States and beyond, with the goal of addressing important questions in biology, chemistry, and clinical sciences through intensive ...

What is proteomics PDF?

Proteomics involves the applications of technologies for the identi cation and quanti cation of overall proteins present content of a cell, tissue or an organism.

What are the types of mass spectrometers used in proteomics?

For proteomics research, four types of mass analyzers are commonly used: quadrupole (Q), ion trap (quadrupole ion trap, QIT; linear ion trap, LIT or LTQ), time-of-flight (TOF) mass analyzer, and Fourier-transform ion cyclotron resonance (FTICR) mass analyzer.
