Question

A researcher is using a modified version of frap. she has devised a technique that allows her to label all the peripheral membrane proteins with a fluorescent tag, and has bleached a specific area of the cell membrane. after 24 hours, she notices that fluorescence has returned to the bleached area. what can she deduce from this experiment?

Answer 1

Since the fluorescence has came back to the bleached area she can come to a conclusion that cell membrane and the Peripheral membrane proteins do not always belong together. FRAP name itself suggest the fluorescence is recovered after the process of photo bleaching and this helps with the study of diffusion that happens in the tissues and cells.
