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.
