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. Used to prepare tissue for immunofluorescent localization of
cytoskeletal components. It is also used for tissue preparation for in situ hybridization with nucleic
acid probes.

Solvent used in the last stage of dehydration of tissue for epoxy embedding.
Quetol 651 Embedding Kit HO7g .............................................
Fast penetrating epoxy embedding medium for EM and LM. Water miscible. Polymerized blocks
section easier than in ordinary epoxy resin mixture and show excellent electron image contrast. Acts
as a dehydrating agent. Technical Data Sheet #297
Kit Contains: 1x100ml Quetol 651, 1 x 250g NSA, 1. 30ml DMP-30
Unicryl Resin EMU6f .......................................................
A unique, largely hydrophilic, acrylic resin, developed for universal use in LM and
EM applications. When fully polymerized, Unicryl demonstrates excellent cutting
characteristics. Sectioning surface follows the contours of the tissue during cutting
action, producing a highly exposed surface of proteins and nucleic acids for
subsequent immunohistochemistry techniques. Resin preserves these structures
without interacting or cross-linking with them. Provides optimum sectioning and
staining for animal, plant and microbiological tissues for Light Microscopy and
Electron Microscopy. Unicryl is provided as a ready-to-use single solution. No mixing
required. Resin remains liquid to -30°, Stable for one year at 4° C.
