Beschreibung

Allgemeine Beschreibung

Ein metachromatischer Farbstoff geeignet für eine Vielzahl von histologischen Färbungen.

Anwendung

Toluidine Blue O along with light-emitting diode has been used as a photosensitizer to control in vitro biofilms and to kill gram-negative bacteria.

Biochem./physiol. Wirkung

Toluidine Blue O (TBO) is a thiazine dye of the quinone-imine family and is cationic in nature. It has been employed in polychromatic staining of paraffin embedded plant cell walls. TBO can be removed from its aqueous solution by using an effective adsorbent, clinoptilolite. TBO and fixed output laboratory laser light source are used together to destroy variety of oral bacteria associated with dental caries. This metachromatic nuclear stain is often used in place of thionin or methylene blue. It also serves as a component of a tribasic stain along with Malachite Greenand Basic Fuchsin.

Eignung

Zertifiziert für den Einsatz in der metachromatischen Färbung von Mastzellen und Knorpel nach der Churukian-Schenk-Methode und der Nocht-Methode für Paraffinschnitte.
