Luminol 215-222 mitochondrially encoded cytochrome c oxidase II Homo sapiens 44-50 16455289-2 2006 This method is based on the fact that both Co(II) and Cr(III) catalyze the luminol-H(2)O(2) CL reaction, and that their catalytic activities are significantly different on the same reaction condition.
