title: Light-microscopic detection of acidic glycoconjugates with sensitized diamine procedures.
abstract: To enhance the efficiency and specificity of diamine methods in light microscopy, these methods were sensitized by silver enhancement in combination with trichloro(ethylene) platinate (KTP). The sensitized diamine methods consisted of a diamine (high or low iron diamine: HID or LID), KTP, borohydride reduction (BH) and a physical development (PD) sequence. The new methods have been successfully applied to routinely prepared tissue sections obtained from rat organs, such as salivary glands, stomach, colon, kidney, lung and trachea. In the tissues subjected to the sensitized diamine methods, weakly diamine-stained histological structures exhibited vivid positive reactions. The combined sensitized diamine methods and selective procedures, such as enzyme digestion and chemical modification, have substantiated that these methods were of sufficient efficiency and specificity.
