This product is intended for in vitro diagnostic (IVD) use. en Fungal cell wall polysaccharides are oxidized to aldehyde groups by the GMS II Oxidizer reagent. Chromic acid suppresses weaker background staining of collagen fibers and basement membranes. The GMS II Neutralizer reagent removes excess chromic acid. The GMS II Silver A reagent provides the silver ions. The GMS II Silver B reagent provides the alkaline conditions, which reduce the silver ions to metallic silver. The GMS II Toner reagent contains gold chloride to form a more stable gold complex and remove the yellow tones from the tissue. The GMS II Fixer reagent, with thiosulfate, stops the reaction and removes any unreduced silver from the section. The GMS II Light Green Counterstain is applied to provide a contrasting background.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.
