A Assembly process of CEAS and verification by PAGE electrophoresis. B Fluorescence spectroscopy validation of CEAS assembly. C Optimization of concentration ratio of CEAS assembly components. D Optimization of Mg2+ concentration in the assembly buffer. E Optimization of the number of hemin spacer bases. F Optimization of CEAS assembly method. Error bars represent standard deviations of three independent experiments. The right Y-axis S/B represents the ratio of signal to blank
