An attempt was made to develop immunologic probes directed against follistatin/activin-binding protein (ABP), for use in investigating the distribution of ABP in various tissues. Five oligopeptides corresponding to different regions of the predicted ABP amino acid sequence (peptides 1-12, 28-43, 123-134, 270-281 and 300-315) were synthesized chemically, and coupled to Limulus polyphemus hemolymph hemocyanin. The peptide-hemocyanin conjugates were then used to immunize rabbits, and the immunoresponses were monitored by enzyme-linked immunosorbent assay. Reactivity of the antipeptide antisera with ABP was determined by SDS-polyacrylamide gel electrophoresis and immunoblotting analysis. All of the peptides produced immune responses. The antiserum to peptide 123-134 recognized all forms of ABP, whereas the antiserum to peptide 300-315 reacted specifically and sensitively with the long forms of ABP. These two antisera exhibited only a limited cross-reaction with other proteins or none at all. Therefore, they will be useful for studying the distribution of ABP in various tissues.
