摘要

Abstract: We developed a new water-soluble phthalocyanine, activated for coupling to antibodies by N- hydroxysulfosuccinimide. The efficiency of anti-CA125-phthalocyanine conjugates was compared to free phthalocyanine in a human ovarian carcinoma model in tissue culture. In both cases a dose dependent cell killing was observed after irradiation with a Titanium sapphire laser at 675 nm and 50 J/cm$+2$/, but incubation with antibody-coupled phthalocyanine resulted in 90% cell mortality with a 60-130-fold lower dye application. !29
