Cyclic voltammograms of the complexes Cyt c -CL_PC-DT(10) (curve a ), Cyt c -CL_PC-DT(20) (curve b ), Cyt c -CL_PC-DT(40) (curve c ), and Cyt c -MUA (curve d ) in 10-mM phosphate buffer (pH 7) at the scan rate of 50 mV/s. CL_PC: cardiolipin-phosphatidylcholine bilayer, DT: 1-dodecanethiol, MUA: 11-mercaptoundecanoic acid.
