I don't know how relevant this may be to you but there are anti-GST
antibodies available which may serve your purpose (I think Pharmacia
sells them but please don't consider this a plug).  If you want an
antibody that uses part of your fusion peptide as an epitope, then
you'd certaintly want to cleave.
