Fig 1: Glutathionylation activity of CLIC1. (A) A representative trace demonstrating glutathionylation activity measured by fluorescence intensity over time for CLIC1, Grx, and GSTO1-1. (B) Area under the curve (AUC) comparison of glutathionylation activities for CLIC1, Grx, and GSTO1-1. Statistical significance was assessed using one-way ANOVA followed by post hoc Tukey’s test. Error bars represent standard deviation (SEM). Statistical significance is indicated as follows: ns = not significant. n = 3.
