Detection of Arginine Post-translational Modifications by Single-Molecule Protein Sequencing on the Quantum-Si Platinum™ Platform
Summary: Aberrant post-translational modifications (PTMs) on arginine residues, namely methylation and citrullination, are closely linked to oncogenic processes. Detection of these PTMs is challenging with current technologies and can be hampered by low abundance and mass differences that are difficult to resolve by mass spectrometry. To overcome these hurdles, we developed methods for PTM detection…
