Weyergang A, Selbo PK, Berg K (2006) Photochemically stimulated drug delivery increases the cytotoxicity and specificity of EGF-saporin. J Control Release 111(1-2):165-173. doi: 10.1016/j.jconrel.2005.12.002
Summary: In this study the authors investigated the use of photosensitizers located in endocytic vesicles that can be induced to release macromolecules upon activation by light. This process is called photochemical internalization, or PCI. Biotinylated EGF was combined with streptavidin-ZAP (Cat. #IT-27), and the compound was applied to various cell lines. The data shows that PCI increases the toxicity of EGF-saporin significantly in EGF receptor-expressing cell lines.
