In my routine protocol, I use 4% paraformaldehyde fixtative and use immunoperoxidase protocol with ABC method. Is that protocol suitable for glutamate antibody?
VGLUT is a specific marker for glutamatergic neurons in hippocampus (presynaptic), glutamate transporters (plasma membrane) and glutamine, glutamine synthase (cytoplasmic). You can use these antibodies to see the localization or labeling.
