And this is basically what the curve describes. So this straight line is part A before we actually Bleached. This is the point at which we bleach. And notice that at that particular section, we no longer see that same type of color, but over time, we see that the color basically returns because of lateral diffusion along that membrane. So this graph demonstrates the recovery of fluorescence in that Bleached area. It confirms the existence of this phenomenon we call lateral diffusion.
