Fig. 1From: NADPH containing superoxide-producing thermostable complex from raspberry, apricot, grape, and grape seeds: isolation, purification, and propertiesThe optical absorption spectra of the isoforms of the NCP-Fe (III) complex were obtained from raspberries, apricots, grapes, and the grape seeds. Optical absorption spectra of weakly opalescent aqueous solutions of isoforms of the O2−-producing complexes NCP-Fe (III) obtained from raspberries a, grapes (b-1), apricots (b-2), and grape seeds (c 1,2) at pH9.5. In the UV region, there is an absorbance characteristic for proteins at 260–280 nmBack to article page
