Dear Mike I have a lot of experience with Tyrosine Hydroxylase on rat
brain frozen slices and by far the best antibodiy I have used is one from
Boeringer cat no 1017 381 this is a monoclonal from mouse hybrid cells. We
use it at quite a high concentration 1:50 but we then reuse it another
twice so 3 sets of sections go through it we are doing free floating
frozens.We get little or no background.I know nothing about Dopamine beta
hydroxylase.  Hope this helps   Good luck Mary
