Abstract

Live cell imaging is a powerful tool for understanding the function and regulation of membrane proteins. In this review, we briefly discuss 4 fluorescence-microscopy-based techniques for studying the transport dynamics of membrane proteins: fluorescence-correlation spectroscopy, image-correlation spectroscopy, fluorescence recovery after photobleaching, and single-particle and (or) molecule tracking. The advantages and limitations of each approach are illustrated using recent studies of an ion channel and cell adhesion molecules.
