Abstract

The topoisomerase (topo) I-DNA covalent complex represents an attractive target for developing diagnostic antibodies to measure responsiveness to drugs. We report a new antigen, peptide 2, and four murine monoclonal antibodies raised against 2 that exhibit excellent specificity for recognition of 2 in comparison to structurally similar peptides by enzyme-linked immunosorbent assays. Although topo I-DNA complex detection was not achieved in cellular samples by these new antibodies, a new strategy for antigen design is reported.
