TAMRA (tetramethylrhodamine) is a xanthene dye of rhodamine series. This fluorophore is being used for quite a long time for the preparation of dual labeled qPCR TaqMan oligonucleotide probes containing TAMRA and fluorescein (FAM).
Just like many other xanthene fluorophores, TAMRA is a available as two isomers (5- and 6-isomer) which have nearly identical optical properties. This product is an isomerically pure 5-TAMRA.
TAMRA NHS is an amine reactive reagent. It can be used for the labeling of proteins, peptides, and modified oligonucleotides containing amine groups.

Coumarin 343 X azide
Coumarin 343 is a blue emitting fluorophore that can serve as a FRET donor for fluorescein (FAM). This azide derivative can be conjugated with alkynes by Click chemistry. An extended linker arm between the fluorophore and the azide group enhances solubility, and provides spatial separation between the dye and the biomolecule.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.FAM DBCO, 6-isomer
Cyclooctyne derivative of fluorescein (FAM) for copper free Click chemistry reaction with azides. Contains pure 6-isomer of fluorescein.General properties
