| General description: | An important fluorophore prepared in high purtity with a detection limit of TMR-labeled amino acids by capillary electrophoresis of approx. 600 molecules. Readily excited by the 546 nm spectral line from mercury-arc lamps used in fluorescent microscopes, and is intrinsically more photostable than fluorescein. |
