Fig. 2From: Purification and characterization of a cytochrome c with novel caspase-3 activation activity from the pathogenic fungus Rhizopus arrhizus a Elution profile of native R. arrhizus cyt c on a Superdex 75 column. b 15Â % SDS PAGE gel showing the peak fraction (lane-1), Molecular weight marker (lane-2). Band marked with an arrow indicate the position of protein band identified as cyt c. c Absorption spectra of the oxidized (---) and reduced form (_) of the native R. arrhizus cyt c. The oxidized form shows a peak in the Soret region at 409Â nm while in the reduced form the Soret peak shifts to 415Â nmBack to article page
