Light and electron microscopic analysis of projection neurons retrogradely labeled with Fluoro-Gold: notes on the application of antibodies to Fluoro-Gold

Fluoro-Gold has been a very popular fluorescent tracer used recently for retrogradely labeling projection neurons. In this study we described the advantages of using antibodies to Fluoro-Gold in conventional immunohistochemical reaction protocols to further extend the usefulness of this tracer for both light and electron microscopic neuroanatomical studies.
