    AnnotationVarious resins (Lowicryl, LR White, LR Gold, Unicryl) used for embedding were compared for their ability to reveal antigens for immunogold labelling on their surface. Their surfaces after cutting with a diamond knife were observed using atomic force microscopy, and results statistically analyzed. The LR White resin in combination with HPF/FS was shown to be able to be successfully used for fine ultrastructural immunocytochemistry. Methods were presented allowing detection of clustering or colocalization of antigens/gold particles. A complete set of tools is now available for reliable detection of gold particles in EM images, their statistical evaluation and production of convenient outputs for publication of results. The plug-ins are useful addition to image analysis software accompanying modern CCD cameras for electron microscopes.
