You are attempting to re-create the mouse/human hybrid cell fusion experiment described in your screencasts. You believe you are performing the procedure the same as it was initially performed, but it takes only half the time for the fluorescent proteins to evenly distribute. Which one of the following statements most likely describes the reason for the difference in your data?
a. The labeled cells were taken out of the refrigerator and used immediately, instead of being allowed to come to room temperature.
b. Different colored fluorescent labels were used, and the difference in wavelength needed to produce the fluorescence impeded the movement of the labeled proteins.
c. More of the phospholipids in this procedure were saturated than in the original experiment.
d. The phospholipids in this procedure had a shorter average fatty acid tail length than in the original experiment.
e. None of the above statements provide a likely explanation for the difference in experimental data between your experiment and the original experiment.
