TAMRA (tetramethylrhodamine) is a well known fluorophore that has a long history of use in biomolecule labeling. TAMRA can serve as a FRET acceptor for FAM (fluorescein).
TAMRA amine is a derivative having a primary amine group that can be conjugated with various electrophiles like activated esters, epoxides, etc., used in reductive amination reactions, and in enzymatic transamination.

BDP R6G amine
Amine derivative of BDP R6G, borondipyrromethene dye matching Rhodamine 6G (R6G) channel. The terminal aliphatic amine group can be conjugated with various electrophiles.Coumarin 343 X NHS ester
Coumarin 343 is a blue emitting dye that can serve as a FRET donor for fluorescein (FAM). This structure features a linker between Coumarin 343 fluorophore, and the functional group. It provides better solubility, and spatial separation between the dye, and the functional group.Sulfo-Cyanine5.5 amine
Sulfo-Cyanine5.5 is a far red/NIR fluorophore possessing high hydrophilicity and aqueous solubility. The dye displays good brightness in far red region due to outstanding molar extinction coefficient. This is amine derivative which is reactive towards electrophiles. It can also be used for enzymatic transamination labeling.General properties
