Q Exactive (Thermo Scientific)Q Exactive (Thermo Scientific)
It is a hybrid mass spectrometer, which combines high-performance quadrupole precursor selection with high-resolution, accurate-mass Orbitrap™ detection. Principally used for protein identification and quantification in complex samples (e.g. cell lysates), as well as identification of post-translational modifications.

It is used to measure molecular weight of intact proteins, peptides or nucleic acid fragments.
Proteomics and Mass Spectrometry Core Facility provides proteomic services to the researchers from the Jagiellonian University and to external users from academia and industry. We apply state-of-the-art methods for analyzing peptides and proteins, including their post-translational modifications (PTMs). We perform complete proteomic workflow that includes sample preparation, mass spectrometry measurement and data analysis. We also offer support in the conceptual design of experiments to apply the best strategy for each research question.

Proteomics is a comprehensive, large-scale analysis of the entire protein complement of a cell line, tissue, or organism. Mass spectrometry (MS) as a robust, sensitive and precise technique, enables the study of proteomes providing information on protein abundances, post-translational modifications and protein-protein interaction networks. In shotgun proteomics, proteins are first digested with protease, and then the resulting peptides are separated by liquid chromatography and analyzed by MS. As a result, in a large-scale proteomic experiment, thousands of different proteins can be identified and quantified, which can be utilized to i.a. characterize two biological states, elucidate mechanisms of disease, detect diagnostic markers or drug targets.
MS is also a powerful tool to analyze single protein providing mass determination of intact molecule, confirmation of protein identification, characterization of PTMs, detection of potential truncations and mutations.
