A peptide can be labeled with a single or multiple dye(s) at the peptide N-terminus, C-terminus, or internally, for applications in protein interaction studies, to trace the presence of biomolecules in cells, enzyme activity assays, etc.
For peptides labeled with a dye and quencher, see our FRET peptides page.
