If your first Ab is RABBIT anti mouse and your second Ab is goat 
ANTI-RABBIT then all you will detect is the coating primary Ab.

A better series would be:

Rabbit anti-ENAC
blocking protein
Mouse anti-ENAC
Enzyme-conjugated goat anti-mouse IgG

Whatever antibody you decide to use it is important to keep track of the 
animal it was made in as well as its specificity.

I have used the Nunc plates for ELISAs and I find that they work well. NAYY
