A removable embedding medium for thin and thick sections. In thicker sections the exterior surface of mitochondria can be observed whereas in resin-embedded thin sections the mitochondria are most frequently observed in a cross section. DGD is used to prepare tissue for immunofluorescent localization of cytoskeletal components. Also used for tissue preparation for in-situ hybridization with nucleic acid probes.

MW = Molecular weight of PEG.
