Fig. 3.
Relaxivity and absorbance measurements of substrates in the presence of HRP/MPO. Longitudinal relaxivity of substrates I and II in HRP/GOX reaction mixture (A) and their absorbance in HRP/H2O2 mixture (C) are shown in the first column. Longitudinal relaxivity of substrates I and II in MPO/GOX reaction mixture (B) and their absorbance in MPO/H2O2 mixture (D) are shown in the second column.
