Abstract

AbstractDuring the last few decades, correlative fluorescence light and electron microscopy (FLM-EM) has gained increased interest in the life sciences concomitant with the advent of fluorescence light microscopy. It has become, accompanied by numerous developments in both techniques, an important tool to study bio-cellular structure and function as it combines the specificity of fluorescence labeling with the high structural resolution and cellular context information given by the EM images. Having the recently introduced single-molecule localization microscopy techniques (SMLM) at hand, FLM-EM can now make use of improved fluorescence light microscopy resolution, single-molecule sensitivity and quantification strategies. Here, currently used methods for correlative SMLM and EM including the special requirements in sample preparation and imaging routines are summarized and an outlook on remaining challenges concerning methods and instrumentation is provided.
