[Histonet] immuno stain for nerve in arterial wall

[C B]

We had an investigator inquire about flourescent immuno stains for nerve in 
arterial wall (not sure what species they are working with).  I've never worked 
with nerve before.  Can someone give me some advice about what primary should I 
be searching for?  I realize I have to look in to species cross reactivity once 
I get that information, but I don't even know what to "search" for.
Thank you,
