A peptide release system using a photo-cleavable linker in a cell array format for cell-toxicity analysis

A novel peptide-array format system with a photo-cleavage linker for cellular toxicity analysis was constructed. In this system, a peptide was immobilized on a commercially available plate bottom via the photo-cleavable linker. UV light irradiation on the desired wells releases the peptide from the plate bottom, and then the cytotoxic behavior of the peptide can be monitored.
