Introduction

Gold chloride, 0.6% solution is a component of many special staining kits, such Grocott kit, stabilized, and P.A.S.M. Jones, stabilized (staining according to Gomori Jones). In those kits gold chloride provides toning of the section’s image, and also stabilization of the dye on the section. After using gold chloride solution, it is usually followed by counterstain, such as Nuclear Fast Red (Kernechtrot) or Fast Green stain.
