E)SDS-PAGE

Question

Quizplus · Accepted Answer

Optical tweezers can be used to trap integral proteins and drag them through the membrane with a known force, using forces generated by a focused laser beam. This technique yields information about the presence of membrane barriers. FRAP and fluorescence recovery after photobleaching are techniques used to study protein mobility within the membrane, while SPT is used to study individual molecules in the membrane. SDS-PAGE is a technique used for protein separation and identification. Therefore, the best choice for the given question is D, Optical tweezers.
