5-TAMRA, SE

5-TAMRA, SE is the single isomer of the amine reactive carboxytetramethylrhodamine (TAMRA) succinimidyl ester.   5-TAMRA, SE is predominantly used for labeling peptides and proteins while 6-TAMRA, SE is often used for labeling nucleotides and sequencing nucleic acids.  The single TAMRA isomers are increasingly preferred for labeling peptides and nucleotides because they give better resolution in HPLC purification that is often required in the conjugation processes.
