Tetramethylrhodamine-5-maleimide is the purified single isomer of tetramethylrhodamine-5 (and 6)-maleimide mixed isomers. It is widely used for thiol modifications of peptides and proteins. It is preferred for some complicated biological applications where reproducibility is more critical than material cost since the minor positional difference between the 5-isomer and 6-isomer might significantly affect some biological properties of the underlying conjugates. The 5-isomer is predominantly used to label peptides and proteins.
