Safety Data Sheets

Novel photo-crosslinking amino acid, which can be incorporated into proteins by cultivation or by chemical synthesis into peptides and other synthetic molecules. Irradiated with UV (ca. 360 nm) for 10 min on ice yields a highly reactive carbene species that rapidly reacts with neighboring molecules to form an irreversible covalent bond.
