Colloidal Gold

Book excerpt: Since its introduction in 1971, the development and application of colloidal gold as a marker in electron microscopy has been phenomenal. This state-of-the art, multi-volume treatise provides researchers, technicians, teachers, and students with the most comprehensive coverage of the principles and methodology of colloidal gold microscopy available today. This universal method is applicable to most microscopical systems including optical microscopy, scanning, transmission and high voltage electron microscopy, and photoelectron, photon, fluorescent darkfield and epipolarization microscopy. Colloidal gold allows high and low resolution studies, enzyme and nucleic acid labeling, study of dynamic cellular processes, and virus detection. - Principles, methods, and applications of colloidal gold methodology in cytochemistry and immunochemistry - Methods for preparing colloidal gold particles of different sizes - Protein A-gold, protein G-gold, and lectin-gold techniques - The use of resins and thin cryosections - Multiple labeling
