Correlative fluorescence and electron microscopy on ultrathin cryosections: bridging the resolution gap

J M Robinson et al. J Histochem Cytochem. 2001 Jul.

Abstract

Microscopy has become increasingly important for analysis of cells and cell function in recent years. This is due in large part to advances in light microscopy that facilitate quantitative studies and improve imaging of living cells. Analysis of fluorescence signals has often been a key feature in these advances. Such studies involve a number of techniques, including imaging of fluorescently labeled proteins in living cells, single-cell physiological experiments using fluorescent indicator probes, and immunofluorescence localization. The importance of fluorescence microscopy notwithstanding, there are instances in which electron microscopy provides unique information about cell structure and function. Correlative microscopy in which a fluorescence signal is reconciled with a signal from the electron microscope is an additional tool that can provide powerful information for cellular analysis. Here we review two different methodologies for correlative fluorescence and electron microscopy using ultrathin cryosections and the advantages attendant on this approach.
