Light-activated bioorthogonal non-canonical amino acid tagging (laBONCAT). Photocaged non-canonical amino acids (ncAA) become available for stochastic incorporation into newly translated proteins following directed light exposure. Bioorthogonal handles installed by ncAAs can be exploited for protein purification prior to quantitative proteomics or fluorescent tagging for visualization.
