Yip WL, Weyergang A, Berg K, Tonnesen HH, Selbo PK (2007) Targeted delivery and enhanced cytotoxicity of cetuximab-saporin by photochemical internalization in EGFR-positive cancer cells. Mol Pharm 4(2):241-251. doi: 10.1021/mp060105u
Summary: Photochemical internalization (PCI) releases macromolecules from endocytic vesicles using photosensitizer activation by light. This technique allows the release of endocytosed molecules before degradation occurs in the lysosome. The authors demonstrate the proof-of-concept for this technique by combining biotinylated cetuximab (a chimeric monoclonal antibody to the EGFr) with streptavidin-ZAP (Cat. #IT-27). The conjugate was applied to three different human cancer cell lines, demonstrating enhanced specificity and toxicity against cells expressing the EGFr.
