Fluorescein isothiocyanate (FITC) labeled Dextrans are valuable materials for studying permeability<br />
and microcirculation in vivo . These are used to trace neuronal projections and active transport in<br />
live and unfixed tissue and as neuronal tracers in a variety of species .<br />

A removable embedding medium for thin and thick sections . In thicker sections<br />
the exterior surface of mitochondria can be observed whereas in resin-embedded<br />
thin sections the mitochondria are most frequently observed in a cross section .<br />
DGD (diethylene glycol distearate) is used to prepare tissue for immunofluorescent<br />
localization of cytoskeletal components . It is also used for tissue preparation<br />
for in situ hybridization with nucleic acid probes . Technical Data Sheet #426<br />

Epon Resin 828 is a standard epoxy resin used in formulation, fabrication and fusion technology .<br />
Widely used for embedding and potting . When cross-linked or hardened with appropriate amine<br />
curing agents, very good mechanical adhesive, dielectric and chemical resistance properties are<br />
obtained .<br />
