Aurion Gold Tracers are used to visualize charged moieties in specimens: anionic tracers bind to polycationic moieties (basic proteins e.g. histones, cationic tracers bind to polyanionic moieties (membranes, acidic proteins). “Neutral” BSA coated gold tracers are useful for detecting open connections and tissue damage. Under proper conditions and with suitable microscopical techniques the tracers can also be used to follow cellular events in time.
