Correlative light and immuno-electron microscopy of retinal tissue cryostat sections

Correlative light and immuno-electron microscopy of retinal tissue cryostat sections

Correlative light-electron microscopy (CLEM) is a powerful technique allowing localisation of specific macromolecules within fluorescence microscopy (FM) images to be mapped onto corresponding high-resolution electron microscopy (EM) images. Existing methods are applicable to limited sample types and are technically challenging. Here we describe novel methods to perform CLEM and immuno-electron...

Topographic contrast of ultrathin cryo-sections for correlative super-resolution light and electron microscopy

Fluorescence microscopy reveals molecular expression at nanometer resolution but lacks ultrastructural context information. This deficit often hinders a clear interpretation of results. Electron microscopy provides this contextual subcellular detail, but protein identification can often be problematic. Correlative light and electron microscopy produces complimentary information that expands our...

Correlative light and electron microscopy of the frog adrenal gland cells using adjacent epon-embedded sections.

Correlative light and electron microscopy on the same cells of the adrenal gland of the frog, Rana nigromaculata, fixed in glutaraldehyde followed by osmium tetroxide, was done using the adjacent Epon embedded sections. Electron microscope observation revealed three different types of granule-filled secretory cells; the noradrenaline-storing cells (NA cells) filled with intensely dense and vary...

Correlative Light Electron Microscopy: Connecting Synaptic Structure and Function

Many core paradigms of contemporary neuroscience are based on information obtained by electron or light microscopy. Intriguingly, these two imaging techniques are often viewed as complementary, yet separate entities. Recent technological advancements in microscopy techniques, labeling tools, and fixation or preparation procedures have fueled the development of a series of hybrid approaches that...
