The physical conditions, including diluent pH, salt concentration and duration of bacillus Calmette-Guerin attachment, were determined in in vitro binding assays for soluble and matrix fibronectin. Since soluble fibronectin may block attachment of bacillus Calmette-Guerin to matrix fibronectin in the bladder, the optimal conditions were determined under which matrix fibronectin-bacillus Calmette-Guerin binding was maximal and soluble fibronectin-bacillus Calmette-Guerin binding was minimal. These conditions, which were confirmed in vivo in the murine bladder model, included use of normal saline, pH 7 as diluent for bacillus Calmette-Guerin organisms, with retention of the bacillus Calmette-Guerin suspension for 2 hours.
