The measurement of not only the location but also the organization of molecules in live cells is crucial to understanding diverse biological processes. Polarized light microscopy provides a nondestructive means to evaluate order within subcellular domains. When combined with fluorescence microscopy and GFP-tagged proteins, the approach can reveal organization within specific populations of molecules. This unit describes a protocol for measuring the architectural dynamics of cytoskeletal components using polarized fluorescence microscopy and OpenPolScope open-access software (http://www.openpolscope.org). The protocol describes installation of linear polarizers or a liquid crystal (LC) universal compensator, calibration of the system, polarized fluorescence imaging, and analysis. The use of OpenPolScope software and hardware allows for reliable, user-friendly image acquisition to measure and analyze polarized fluorescence.
