I'm looking for a method of detecting condensed tannins (proanthocyanidins) 
in histological sections of nematodes. Does anyone know of either 1. a 
stain that will identify condensed tannins in histological sections or 2. a 
method of labelling condensed tannins (a chemiluminescent label maybe?) 
before exposure to the nematode that can later be detected in a microscopic 
preparation?

Thanks,
