Reduction and Oxidation Potentials for

Further complicating factors in the choice of an enhancer include degradation of HRP by enhancer radicals [23], pH effects [24] on reduction and oxidation potentials for enhancer and acridan ester, inactivation of enhancer radicals because of dimerization or other reactions, etc. All these, and other, effects of the structures (and because of the kinetics also the concentrations) of enhancer and acridan ester may cause erratic results when optimization studies are conducted. When... 

In a redox reaction, electrons move spontaneously toward atoms or molecules having more positive reduction potentials. In other words, a compound having a more negative reduction potential can transfer electrons to (i.e., reduce) a compound with a more positive reduction potential. In this type of reaction, the change in electric potential A is the sum of the reduction and oxidation potentials for the two half-reactions. The AE for a redox reaction is related to the change in free energy AG by the following expression ...
