Identification of CD20-specific recombinant phages by phage ELISA. Ninety-two clones of recombinant phage were randomly selected from the third round of panning and added to CD20 extracellular peptide-coated microplates. The bound phage was detected with HRP/anti-M13 monoclonal antibody. PBS was used as a blank control, and helper phage M13K07 was used as a negative control. The OD450 nm of 54 clones detected was 2.1-fold higher than the negative control, indicating that 54 of the 92 recombinant phages had high antigen-binding activity.
