5-FAM-LPETGG TFA

5-FAM-LPETGG is a fluorescent peptide that combines the sortase recognition sequence LPETGG with the fluorescent label 5-carboxyfluorescein (5-FAM), characterized by excitation/emission maxima at 492/518 nm. It serves for site-specific labeling of target proteins through sortase-catalyzed transpeptidation.
