Description

Fungal cell walls are rich in polysaccharides known as glucans. Periodic Acid Solution oxidizes these polysaccharides to form aldehydes, which in turn react with the silver ions present in the Working Methenamine Silver Solution and reduce them to form visible metallic silver. Gold Chloride Solution tones the sections and intensifies the reduced silver by forming a silver-gold complex. Sodium Thiosulfate Solution removes any unreduced silver from the tissue sections, followed by Fast Green Stain Solution which produces a light green background to further enhance contrast.
