Descrizione

Applicazioni

Auramine O has been used to study the cuticle/cutin in the epidermis of the pollen presenter in Vangueria infausta.

Azioni biochim/fisiol

Auramine O is used for the staining of acid-fast organisms, coccidia. Auramine O along with carbol generates brilliant yellow fluorochrome of tubercle bacilli. It is effective in detecting positive cases of tuberculosis. Auramine O binds to the mycolic acid in the bacterial cell wall.

Compatibilità

Certified for use by fluorescence microscopy in Churukian′s modification of Truant′s fluorescent method for acid fast bacilli on paraffin sections.
