Descripción

General description

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

Auramine O is used for the staining of acid-fast organisms like coccidia. Along with carbol, it 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.

Application

Auramine O has been used to study its absorption by a natural biopolymer poly (γ-glutamic acid).
