5-carboxytetramethylrhodamine ( 5-TAMRA ) is a red fluorescent dye from the group of rhodamines . It can be classified both in the group of triphenylmethane dyes and xanthene dyes . 5 ‑ TAMRA is used for fluorescent labeling of nucleic acids and proteins . [2] [3] The carboxy group can be converted into a reactive intermediate state with coupling reagents . Alternatively, the succinimidyl ester can be 5-carboxytetramethylrhodamine- N- succinimidyl ester( 5-TAMRA-SE ) can be used for marking. 5-TAMRA is used, among other things, for fluorescent substrates of enzymes , hybridization probes and in FRET .
