Three disulfide linkages of recombinant human brain-derived neurotrophic factor (BDNF) were determined by peptide sequence analysis and characterized by mass spectrometry. The three disulfide bonds for BDNF expressed in Chinese hamster ovary cells include Cys-13-Cys-80, Cys-58-Cys-109 and Cys-68-Cys-111, and the disulfide structure was homologous to that of nerve growth factor.
