Decolorizer, an acid alcohol reagent, is applied to remove the color from all tissue elements other than the acid-fast components. Organisms that remain stained are believed to have selective permeability to the fuchsin.2 The Aniline Blue counterstain provides contrast in the tissue section to enhance organism visibility.This kit is optimized for use on BenchMark Special Stains instruments. The reagents are applied to tissue on microscope slides and mixed over the entire specimen. en
