Proteomics has become a cornerstone of modern biological research, offering dynamic insights that extend beyond genomics. Advances in mass spectrometry, bioinformatics, and data analysis have transformed proteomics into a powerful tool for deciphering disease mechanisms, identifying biomarkers, and discovering therapeutic targets. By systematically navigating the proteome’s vast complexity, researchers can uncover hidden layers of protein expression, modifications, and interactions, providing a comprehensive view of cellular processes and their regulation.

The CNIO Proteomics Core Unit is at the forefront of this transformation, leveraging cutting-edge technologies to tackle fundamental questions in cancer biology. The recent acquisition of the Orbitrap Astral mass spectrometer marks a major milestone, delivering unprecedented sensitivity, depth, and throughput for large-scale, high-resolution proteomic studies. Through close collaboration with CNIO investigators, we integrate quantitative proteomics, functional analyses, and advanced bioinformatics to drive high-impact discoveries that advance cancer research and precision medicine.
