Abstract: With PR81 as a murine monoclonal antibody (mAb) that was prepared against the human breast cancer, the MUC1 receptor specific targeting is possible. In this study, PR81-conjugated bovine serum albumin (BSA) nanoparticles loaded with anticancer drug 5-fluorouracil (5-FU) were developed. Enzyme linked immunosorbant assay (ELISA) results showed high immunoreactivity of PR81 mAb conjugated to nanoparticles towards MUC1 related peptide or native cancerous MUC1 and almost no cross-reaction to non-specific proteins. In vitro experiments were performed to determine the ability of this new drug delivery system on overcoming MCF-7 breast cancer cells in comparison with four other systems. The results revealed that these cell-type specific drug loaded nanoparticles could achieve more cell death as compared to when the 5-FU was used with no carriers. Stability studies of produced drug delivery system proved high immunoreactivity of conjugated PR81 even after 11 days of storage in room temperature.
