This paper develops a photosensitized strategy for protein labelling using N-substituted pyridinium salts and a quinolinium scaffold, achieving efficient labelling in minutes with high selectivity for tryptophan residues.

The paper uses native mass spectrometry to analyze the oligomerization states of SARS-CoV-2 E protein, poliovirus VP4, and HIV Vpu, revealing differences in their assembly patterns.
