A highly specific immuno-nanoparticle (ADR-NP-Ab) has been constituted by chemically coupling a monoclonal antibody BDI-1 to albumin nanoparticle containing adriamycin (ADR-NP). Different molecular ratios of antibody to ADR-NP were tried to determine the optimal condition for preparing the immuno-nanoparticle. The results of immunofluorescence and microphotographic analysis showed that the activity of ADR-NP-Ab was well preserved. The result of the cytotoxicity of ADR-NP-Ab in vitro assay showed strong killing activity of ADR-NP-Ab to bladder cancer cells (EJ), while no apparent cytotoxic activity to non-targeted human colon carcinoma cells (Lovo) was observed.
