title: [Antigenic structure of the Bordetella pertussis pertactin Pro-rich segment 536-566. I. Preparation and analysis of antisera to synthetic peptides].
abstract: Rabbit antibodies to four synthetic peptides from the Pro-rich sequence of B. pertussis P.69 have been obtained. Prior to immunization, peptides KAPPAPKPAPQPGPQPP (17P), QPPQPQPEAPAPQP (14P), GPQPPQPPQP (10P) and PGPQPP (6P) were conjugated with keyhole limpet hemocyanin (KLH). Immunoenzymatic analysis revealed the following antibody titers: 1:4,000,000 (17P), 1:64,000 (14P) and 1:256,000 (10P). Serum antibodies to KLH-6P did not react with 6P-coated plates but interacted with the hexapeptide in the ovalbumin-6P conjugate. The sera to KLH-14P effectively recognized glutaraldehyde-formed epitopes. Using indirect immunoassay and competitive assay, it was shown that antisera to KLH-17P, KLH-14P, KLH-10P and KLH-6P did not react with unrelated antigens. Sera and affinity-purified antibodies to peptides 10P, 14P and 17P recognized native pertactin with variable efficiency.
