ABSTRACT:
A composition is disclosed for transferring and adhering tape-mounted hisogical sections, to specimen mounting surfaces, usually glass microscope slides to expedite and simplify the safe removal of the mounting tape and the subsequent processing of the slide-mounted section. The composition is a curable polymeric mixture which has high tack prior to curing, is substantially non-diffusable and non-flowable into tissue sections and, after curing, has a refractive index substantially similar to that of the specimen section and is non-labile to conventional histological solvents and stains. A preferred composition comprises diacrylate-terminated polyurethane, a diacrylate ester of an epoxy resin and a diethoxyacetophenone initiator. It is usually formed onto the mounting surface as a solution in a conventional organic solvent, such as isopropanol or toluene.
