title: Cadmium-isocitrate complex: its stability as a function of ionic strength.
abstract: The complexation of cadmium by isocitrate has been studied at 25 degrees C and pH 7.5 in a range of ionic strength from 0.01 to 0.16. The formation constant of the complex between cadmium and tribasic isocitrate varies from 860 M-1 at mu=0.16 to approximately 24,500 M-1 at infinite dilution. These data allow the distribution of the chemical forms of cadmium added to the incubation mixtures for tha assay of NAD-dependent isocitrate dehydrogenase to be calculated.
