If you have IgGs for this protein, why do you bother to make Ab again? :)
I think you were talking about coupling rather than binding, right?

Anyway, for those small,  hydrophilic proteins, you probably need to
conjugate them to some generic proteins like BSA, KLH or thyroglobulin.
Simply treat them as synthetic peptide haptens. Another trick is to
immunize animals with either SDS-PAGE or nitrocellulose powders if your
protocol allows you do that.
