PSA-spiked human female serum analyzed with the sandwich microarray at three different capturing antibody concentrations (H117: 35 µgmL−1, 77 µgmL−1 and 154 µgmL−1). Increased assay sensitivity was observed with the elevated concentration of the capturing antibody (H117). The negative signal also increased at the higher concentrations of H117.
