Amperometric responses for individual standard solutions of IL-6 and IL-8 in undiluted calf serum at −0.2 V vs. Ag/AgCl developed by injecting a mixture of 1 mM HQ and 0.1 mM H2O2 for (A) IL-6 and (C) IL-8, also showing calibration plots for (B) IL-6 and (D) IL-8 standards. Error bars represent standard deviations (n=8) for the eight electrodes of a single immunoarray.
