Abstract

Raster Image Correlation Spectroscopy (RICS) is a confocal image analysis method that can measure the diffusion and interactions of fluorescently labeled molecules in real time in solution and in living cells. RICS is easy to implement on commercial confocal microscopes and allows detailed investigations of complex biological systems and pathways. The method is especially robust for measurements in living cells using commonly used labels such as fluorescent proteins. Moreover, since its invention in 2005, the robustness and applicability of RICS has been significantly increased to allow, e.g., straightforward kinetic analyses, advanced image segmentation, parameter mapping, and multi-species analysis. In this review, we describe the methodological principles of RICS in a manner that is accessible to a broad readership, position RICS in relation to other fluorescence fluctuation techniques, highlight recent methodological advances and present exemplary applications of the method. With this review, we hope to facilitate the implementation of this powerful method into the everyday repertoire of confocal imaging approaches.
