Half-cell redox potentials and Open-circuit cell potentials are monitored using a divided, Open-circuit potentiometric cell via Hach Lange GmbH XR200 Hg/[Hg.sub.2]S[O.sub.4] reference electrodes (Part No.
The spectrophotometric multiple-wavelength pH-titration was carried out as follows: in a first step, the standard emf values, Eo, of the potentiometric cell were evaluated from titrations of a measured amount of an acidic solution, at the same conditions of temperature, ionic strength and solvent composition to be used in later experiments using KOH solutions in the same solvent and ionic strength as the titrant, and checking the calibration parameters from the Gran plots [40, 41].
For the thrombin detection assay, the potentiometric cells were introduced in a solution in which successive aliquots of thrombin solutions were added giving rise to a total thrombin concentration starting from 0.5 nM up to 800 nM, which is approximately the maximum physiological levels in blood [29, 30].
