Figure 5: (A) Ep values of DPV for the same serum sample (diluted in PBS 1:4) obtained in four subsequent experiments in the presence of CPC (100 mmol L-1) without electrode polishing. (B) Ip values at the same conditions. (C) Area values at the same conditions. In each experiment, the samples were analyzed every 1, 40 and 80 minutes after thawing. All measures were carried out in triplicate.
