(A) ThT fluorescence spectra of 0.2 mg mL−1 α-LA in the absence (
) and presence of 0.01 (
), 0.02 (
), 0.03 (
), 0.04 (
), 0.05 (
), 0.07 (
), 0.1 (
), 0.2 (
), 0.4 (
), 0.8 (
), 1.0 (
), 2.0 (
) and 5.0 (
) mM SHMP at pH 2.0. (B) Fluorescence intensity at 485 nm was plotted against SHMP at pH 2.0. The error bars represent the standard errors of the means estimated from at least three individual measurements.
