  • Embedding media suitable for the preparation of thin sections of embedded biological materials
    Patent number: 4680362
    Abstract: The invention concerns methods and embedding media components for producing essentially non-polar and polar embedding media. The non-polar embedding medium comprises ethyl methacrylate, n-butyl methacrylate, 1,3-butanediol dimethylacrylate, and a small amount of polymerization initiator. The polar embedding medium comprises 2-hydroxyethyl acrylate, 2-hydroxypropyl methacrylate, n-butyl methacrylate, optionally methoxyethyl methacrylate, ethoxyethyl methacrylate, 1,3-butanediol dimethacrylate, and a small amount of polymerization initiator. The embedding media of the invention are particularly suitable for the preparation of a polymer embedded biological material for light or electron microscopic study of thin sections thereof. The embedding media can be polymerized at low temperature and UV light employed for initiating polymerization.
