Fig. 1From: ECL: an exhaustive search tool for the identification of cross-linked peptides using whole databaseAn illustration of cross-linked peptides’ dissociation pattern. Two chains’ lysines are linked. Green markers indicate linear ions, and red markers indicate cross-linking ions. A chain’s linear ions only contain that chain’s amino acids. A chain’s cross-linking ions contain that chain’s amino acids, a cross-linker, and another whole chainBack to article page
