Difference in the dissociation rate was determined by one-way ANOVA, which is performed on the logarithm of the koff values. *, P < 0.1, and ****, P < 0.0001 vs dark condition for 500 and 380 nm conditions, respectively.
Dissociation rate of the indicated NAM.
t1/2 is the half-life of dissociation.
