Brilliant Blue G is a methanol based stain which is especially designed for staining protein in polyacrylamide gels, but will also stain protein in agarose gels (IEF). The stain contains methanol and acetic acid so gels do not require fixing prior to staining. Water is added directly to the bottle to produce 1 liter of ready-to-use staining solution.

Auramine O has been used to study the cuticle/cutin in the epidermis of the pollen presenter in Vangueria infausta. 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. Certified for use by fluorescence microscopy in Churukian′s modification of Truant′s fluorescent method for acid fast bacilli on paraffin sections.
