Tyrosine Hydroxylase immunostaining?

Hi all,

I am doing a tyrosine hydroxylase (TH) immunostaining experiment on Dopamine neurons in VTA. I just decided to use a fluorescence microscope, so I would need to use the fluorescent detection. I want to work with Mouse anti-human TH (primary antibody) and Horse anti-mouse IgG (secondary antibody), but my supervisor asked me to find the best antibodies to have the best results. I would appreciate if someone help me to find the right primary and secondary antibody.

Thank you so much.
