Overview of the antibody development process. (A) A suitable, vasoinhibin-specific epitope at the loop 1 region (L1) was identified on the basis of a three-dimensional model of vasoinhibin as reported by Robles et al. (B) Antibodies obtained after immunization with two immunizing peptides comprising neighboring L1 regions were selected by their affinity to PRL, to the immunizing peptides, as well as to coated vasoinhibin antigen. (C) A sandwich ELISA consisting of two monoclonal, vasoinhibin-specific antibodies was set up.
