Fig. 5. Antibody-photoCORM conjugates (Ab-photoCORMs) deliver cytotoxic levels to ovarian cancer cell lines via immunosorbent assay. (A) Western analysis of whole cell lysates of cell lines OVCAR-5 and SKOV-3, probing for antigens recognized by a family of Ab-photoCORMs. (B) Cell viability, as measured by cellular reduction of MTT, of OVCAR-5 and SKOV-3 24 h post-immunosorbent assay utilizing 2 µg mL^–1 Ab-photoCORM conjugates. (C) Dose-dependency of α-HCAM-photoCORM, compared to α-Control-photoCORM, on cell viability. Data representative of n = 3 independent experiments. (*p < 0.05).
