Proteomics

Over the last two decades, significant advances seen in technology and new methodologies have made proteomics an extremely powerful tool for protein scientists, biologists and clinical researchers. The introduction of the timsTOF Pro coupled with the revolutionary PASEF® acquisition mode is not only breaking new boundaries in speed, sensitivity, selectivity and robustness, but also enabling 4D-Proteomics™ approaches, allowing scientists to routinely explore parts of the proteome not previously accessible.

Direct protein analysis from tissue or biofluids raises a variety of analytical challenges. Protein expression varies depending on the genetic background of an individual, but also on time, localization, and as a physiological response to external stimuli (stress, disease, aging, effort …). Moreover, because of the combined effects of alternative splicing, point mutation, post-translational modifications and endogenous proteolysis, a given protein (gene expression product) can be expressed as many different proteoforms, each having a dedicated biological activity. Fully addressing that complexity can only be achieved using orthogonal approaches. Bruker offers a dedicated panel of solutions to deal with these challenges.
