Abstract
The synthesis of a set of tetrazine-bearing fluorogenic dyes suitable for intracellular labeling of proteins in live cells is presented. The red excitability and emission properties ensure minimal autofluorescence, while through-bond energy-transfer-based fluorogenicity reduces nonspecific background fluorescence of unreacted dyes. The tetrazine motif efficiently quenches fluorescence of the phenoxazine core, which can be selectively turned on chemically upon bioorthogonal inverse-electron-demand Diels-Alder reaction with proteins modified genetically with strained trans-cyclooctenes.Entities:
