Polarized Total Internal Reflection Fluorescence Microscopy (pTIRFM) allows for real-time observation of plasma membrane deformations. The technique provides insights into the dynamics of biological processes requiring rapid and localized changes in membrane shape. Such processes include exocytosis, endocytosis, cytokinesis, and cell motility. In this chapter, we describe how to implement a polarization-based TIRF imaging system to monitor exocytosis in adrenal chromaffin cells.
