Curve fitting for IL-1β and IP-10. Visualization of the regression line (blue) fitted for the theoretical concentrations and membrane’s fluorescence readouts of IL-1β (a) and IP-10 (b). The dots are compactly distributed around the predicted line, and the unexplained error is small. The red lines delimited the 95% of CI. The equations of the curves are: a) y = 561.73 × + 8.97 with Pearson’s r = 0.97; b) y = 1830.6 × – 79.4 with Pearson’s r = 0.91. The red dashed lines delimited the 95% confidence interval.
