Antibodies to invertebrate ACH receptor?

[ghyra31]

I am interested in identifying the location of neuromuscular junctions
in turbellarian flatworms.  I have it on good authority that
acetylcholinesterase is present in these animals, but
alpha-bungarotoxin assays for the ACHr are negative. Any suggestions
for antibodies (and their sources) would be greatly appreciated.

Thanks to all respondents
