Inter-linked disulfide bonds connecting peptide chains are homolytically cleaved with 193 nm ultraviolet photodissociation (UVPD). Analysis of insulin demonstrates the ability for UVPD to cleave multiple disulfide bonds and provide sequence coverage of multiple peptide chains in the same MS/MS event...
