Proteomics Mass Spectrometry

Comprehensive and confident proteomic analysis

To better understand the functions of individual proteins and their place in complex biological systems, it’s necessary to measure changes in protein abundance relative to those of the system, and proteomics mass spectrometry makes that possible. Modern proteomics has shifted from its initial qualitative outlook to a continuum of qualitative and quantitative technologies and approaches which include state-of-the-art sample preparation, liquid chromatography separation, high-resolution accurate-mass Orbitrap mass spectrometry, and proteomic software solutions for mass spectrometry data analysis.

We’re supporting successful laboratories in their discovery and study of proteomes as they combine these components into integrated workflows which maximize productivity and enable broader, deeper proteomic analysis. Our proven scientific network, publications, and pioneering solutions, driven by advances in Orbitrap mass spectrometry systems and consumables, are producing novel, stringent and reproducible results that are pushing proteomics research and discovery forward.

Triple quadrupole vs Orbitrap mass spec for proteomic analysis

Triple quadrupole vs Orbitrap mass spec for proteomic analysis

Targeted quantitation is frequently performed on triple quadrupole mass spectrometers such as the Thermo Scientific TSQ family, but it can also be accomplished using the HRAM and MS/MS capabilities of 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.

Proteomics liquid chromatography (LC) separations

Large-scale proteomics experiments are typically analyzed at the peptide level. For successful characterization, peptides and proteins must be separated prior to introduction into the mass spectrometer. Minimizing complexity ensures that peptides and proteins can be detected and sequenced even if they are present at low abundance. The gold standard for peptide separation in bottom-up proteomics is reversed phase (RP)-LC because it offers the broadest peptide coverage. Separation using our low-flow systems easily integrate into proteomics mass spectrometry workflows and seamlessly combine with our Orbitrap mass spectrometers for broader and deeper analyses into the proteome.

Obtain high resolution separations of low abundant peptides in complex proteomic samples using columns with high loading capacity.

Thermo Scientific Trap Column Cartridges Holders with nanoViper fittings do not "grab" the tubing at a single point but seal at the tip without using a ferrule. This gives nanoViper fittings their UHPLC, ensuing virtually dead-volume-free capabilities.

Ensure robust nano and capillary flow LC-MS with Thermo Scientific EASY-Spray LC Columns. The integrated column/emitter design eliminates dead volume and is temperature-controlled for maximum reliability and performance. Rigourously tested to ensure maximum quality, these columns are designed for maximum simplicity and ease-of-use.
