  • Patent number: 7070951
    Abstract: Compositions and methods are provided for dewaxing wax-embedded biological specimens prior to histochemical analysis. The compositions and methods provided can effectively remove wax or improved wax-based embedding materials, particularly paraffin-based, from specimens during preparation for histochemical or other diagnostic analyses, while minimizing danger to users, achieving compatibility with automated use, and maintaining compatibility with downstream histochemical analyses, particularly immunostaining. Compositions of the invention comprise a paraffin-solubilizing organic solvent, a polar organic solvent, and a surfactant. Compositions can further comprise water. The method involves contacting a wax-embedded specimen with the dewaxing composition to solubilize the wax impregnating the specimen prior to histochemical analysis.

  • Patent number: 5578452
    Abstract: A method for restoring immunoreactivity of a tissue, particularly decalcified tissue, fixed width an aldehyde fixative agent and embedded in an embedding medium, usually comprising celloidin, the method comprising the steps of contacting the tissue with an aldehyde releasing reagent solution comprising a solvent and an aldehyde releasing reagent and removing aldehyde released by the aldehyde releasing reagent from contact with the tissue by reacting the aldehyde in a substantially irreversible manner to form a non-aldehyde derivative, and removing excess base from the tissue. A preferred solution for celloidin-embedded decalcified tissue comprises methanolic sodium hydroxide at about one-third saturation.
