MPhAb binding to complement-resistant M. catarrhalis is inhibited by scFv antibody fragments. Plates were coated with serum-resistant strain 9.21R, and a mixture of PhAb and scFv was added. Bound phages were detected by anti-M13 antibody. Inhibition of MPhAb B12 binding by scFv fragments of each of the 10 clones was determined and presented as percentage inhibition of binding in absence of scFvs or KV5. Incubations with MAb KV5 (recognizing HMW-OMP on complement-resistant M. catarrhalis strains) and scFv HM1 (recognizing HMG box protein) served as inhibition controls.
