Synthetic oligopeptides comprising linear or continuous topographic B-cell epitope sequences of proteins might be considered as specific and small size antigens. It has been demonstrated that the strength and specificity of antibody binding could be altered by conjugation to macromolecules or by modification in the flanking regions. However, no systematic studies have been reported to describe the effect of different carrier macromolecules in epitope conjugates. To this end, the influence of carrier structure and topology on antibody recognition of attached epitope has been studied by comparing the antibody binding properties of a new set of conjugates with tetratuftsin analogue (H-[Thr-Lys-Pro-Lys-Gly]4-NH2, T20) sequential oligopeptide carrier (SOCn,), branched chain polypeptide, poly [Lys(Seri-DL-Alam)] (SAK), multiple antigenic peptide (MAP), and keyhole limpet hemocyanine (KLH). In these novel constructs, peptide 9LKNleADPNRFRGKDL22 ([Nle11]-9-22) representing an immunodominant B cell epitope of herpes simplex virus type 1 glycoprotein D (HSV-1 gD) was conjugated to polypeptides through a thioether or amide bond. Here we report on the preparation of sequential and polymeric polypeptides possessing chloroacetyl groups in multiple copies at the α-and/or ε-amino group of the polypeptides and its use for the conjugation of epitope peptides possessing Cys at C-terminal position. We have performed binding studies (direct and competitive ELISA) with monoclonal antibody (Mab) A16, recognizing the HSV gD-related epitope, [Nle 11]-9-22, and conjugates containing identical and uniformly oriented epitope peptide in multiple copies attached to five different macromolecules as carrier. Data suggest that the chemical nature of the carrier and the degree of substitution have marked influence on the strength of antibody binding.
