Amyloid protein aggregation kinetics at different concentrations of apigenin, ectoine, taiwaniaflavone and trehalose (points) and fittings to equation ( 1 ) (surface). X: aggregation data measured by ThT fluorescence intensity at 482 nm or 490 nm (AU). A: experimental data of apigenin. B: taiwaniaflavone data. C: experimental data of hydroxyectoine. D: data of trehalose affecting apomyoglobin kinetics.
