Figure 6From: Comprehensive characterisation of pulmonary and serum surfactant protein D in COPDOxidative induced disruption of the quaternary structure of pulmonary SP-D. Blue native electrophoresis of surfactant protein-D after incubation with an oxygen radical donor (+). Disruption of the multimeric structure (*) can be chemically induced by exposing rr-SP-D or BAL from healthy subjects to 74 mM of the oxidizing agent 2,2-Azo-bis-(2-amidinopropane)-dihydrochloride (+).Back to article page
