6-TAMRA Maleimide [Tetramethylrhodamine-6-maleimide] *CAS 174568-68-4*

6-TAMRA Maleimide

Tetramethylrhodamine-6-maleimide; CAS 174568-68-4

Tetramethylrhodamine-6-maleimide is the other purified single isomer of tetramethylrhodamine-5 (and 6)-maleimide mixed isomers. Compared to the 5-isomer, tetramethylrhodamine-6-maleimide is preferably used for thiol modifications of nucleotides and nucleic acids.
