yes, glutaraldehyde can influence protein conformations and change
immunostaining patterns. some antibodies are prepared using glut-
fixed antigen to stain in glut-fixed tissue. i think this is not the
case for Chemicon anti-TH. try it with straight paraformaldehyde tissue
if you can. 

also, we get good results with TH polyclonal Ab from Eugene Tech
and monoclonal from INCstar. Chemicon was not as good the one time
i tried it.
