Correlative Light and Electron Microscopy (CLEM) is a technique that allows correlation of fluorescent and electron microscopic images. In-resin CLEM is a powerful method that improves correlation accuracy by observing the same resin-embedded ultrathin sections with both fluorescence and electron microscopy. This approach ensures high correlation except for differences in electron beam and fluorescence wavelengths, while improving the Z-axis resolution of the fluorescence signal. In this presentation, we will introduce several techniques of in-resin CLEM. First, we will show in-resin CLEM using fluorescent proteins such as CLEM-Red and CLEM-Green. Next, we will present in-resin CLEM using proximity labeling with biotin ligase. In addition, we will show our newly developed "immuno-in-resin CLEM", which is a method to apply immunological reactions to in-resin CLEM of Epon resin-embedded cultured cells. Finally, we will demonstrate the application of immuno-in-resin CLEM using anti-Iba1 and anti-GFAP antibodies on microglia and astrocytes in the CNS of a mouse model of neuronal ceroid lipofuscinosis. This application shed light on ultrastructural abnormalities of microglia and astrocytes in the CNS of a mouse brain model of neurodegenerative disease.
