Immunocytochemical staining of A498 and control cells when bound with phage ZT-2. Cell-bound phages were detected using anti-M13 phage monoclonal antibody, secondary antibody, and ABC complex. The cells were stained with diaminobenzidine (DAB). (A) shows control cell (B) shows immunocytochemical staining of A498 cells when bound with phages without exogenous sequences (wild-type phage) (C) shows immunocytochemical staining of A498 cells when bound with unrelated phage (D) shows immunocytochemical staining of A498 cells when bound with phage ZT-2.
