FRAP (Fluorescence Recovery After Photobleaching) (A) 1 Immobile fraction Photoech 2 3 Recovery half time Time Bleach 6 Fluorescence intensity in bleach ROI Three cell membrane samples: M, C, and S were fluorescently labeled and were subsequently photobleached. The recovery of fluorescence was monitored and gave the following profile: 100 M S time a. Rank the three cell membranes in terms of decreasing fluidity. Provide an explanation of your ranking based on their FRAP curves and the most probable appearance and composition of the three membranes. b. Draw the expected image of the surface of the three membranes before photobleaching and after fluorescence recovery as viewed under a fluorescence microscope. % fluorescence
