Pyrene‐Conjugated, 2‐Pyridinecarboxaldehyde Derivatives as N‐Terminus‐Specific Tags for MALDI‐ and LALDI‐MS

Rapid Communications in Mass Spectrometry, Volume 40, Issue 8, 30 April 2026.
ABSTRACT Background Proteolytic processing is a fundamental post‐translational modification. Liquid chromatography–tandem mass spectrometry (LC–MS/MS) workflows are powerful for degradomic analyses but inherently sacrifice spatial information, a critical aspect for investigating biological systems such as aberrant extracellular matrix remodeling and ...
