In this study, the preparation of 111In-Bleomycin complex was optimized for temperature, time, concentration and pH during several experiments. The results showed that by the addition of bleomycin to 111In-InCl3 sample (dried under flow of N2) and heating the mixture up to 90-100°C the radiopharmaceutical can be obtained in 99.5% yield and a specific activity of 1.745 Ci/mmol. The final sample was injected into fibrosarcoma-bearing mice via their tail vein. Satisfactory preliminary SPECT images were acquired between 2-4 hours post-injection showing suitable accumulation in fibrosarcoma tumors.
