Proteomics Mass Spectrometry Analysis

Comprehensive and confident proteomics analysis

Identifying peptides from complex mixtures with high-accuracy and high-precision quantification requires a combination of speed, high mass resolution accurate mass (HRAM), and multiple fragmentation techniques. The Thermo Scientific Orbitrap Fusion Lumos Tribrid, Q Exactive, and Triple Stage Quadrupole (TSQ) instrument lines easily perform qualitative and quantitative analysis of complex proteomics samples via ion isolation for MS/MS fragmentation.

In order to identify as many peptides as possible from complex mixtures and achieve both high accuracy and high precision during quantification, a combination of speed, high resolution accurate mass (HRAM), and multiple fragmentation techniques is needed. All available Orbitrap-based platforms capable of ion isolation for MS/MS fragmentation, including the Thermo Scientific Orbitrap Fusion Lumos, the Orbitrap Fusion, and the Q Exactive line of instruments, can perform qualitatitive and quantitative analysis of complex proteomics samples.

Targeted quantitation is frequently performed on triple quadrupole mass spectrometers such as the Thermo Scientific TSQ family, but can also be accomplished using the HRAM and MS/MS capabilities of the Orbitrap-based mass spectrometers. Using the same type of mass spectrometers for discovery and targeted quantitation experiments can simplify the transition to targeted quantitation methods. Thermo Scientific Orbitrap-based mass spectrometers can simultaneously quantify and confirm identification of multiple targeted proteins and peptides even in complex biological matrices.
