TAMRA, SE; 5-(and-6)-Carboxytetramethylrhodamine, Succinimidyl Ester (5(6)-TAMRA, SE), mixed isomers (Invitrogen™)

Tetramethylrhodamine (TMR) is an important fluorophore for preparing protein conjugates. Under the name TAMRA, the carboxylic acid of TMR has also achieved prominence as a dye for oligonucleotide labeling and automated DNA sequencing applications. 5-(and-6)-carboxytetramethylrhodamine, succinimidyl ester is the amine-reactive, mixed isomer form of TAMRA. Single isomer forms of 5-TAMRA SE (Cat no. C-2211) and 6-TAMRA SE (Cat. no. C-6123) are also available.
