This 2-part protocol describes antigen retrieval with Tris EDTA buffer followed by immunostaining. Antigen retrieval can be helpful for aldehyde-fixed, paraffin-embedded samples that don't give sufficient signal with a standard immunostaining protocol. Several antigen retrieval methods exist but, unfortunately, you need to determine empirically which one is most suited to your antibody.
