Allgemeine Beschreibung

Ein wichtiger Fluorophor, hergestellt in hoher Reinheit mit einer Nachweisgrenze für TMR-markierte Aminosäuren durch Kapillarelektrophorese von ca. 600 Molekülen. Er wird leicht von der 546 nm-Spektrallinie von Quecksilberdampflampen, die in Fluoreszenzmikroskopen verwendet werden, angeregt und er ist photostabiler als Fluorescein.

Anwendung

5-Carboxytetramethylrhodamine has been used in fluorophore characterization.

Biochem./physiol. Wirkung

5-Carboxytetramethylrhodamine can be covalently attached to the DNA and is thereby used in studies involving branched and duplex DNA/RNA structures. It is mainly used for single-molecule studies. 5-Carboxytetramethylrhodamine is also used for the labelling of oligosaccharide for laser-induced fluorescence detection.
