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. The method can comprise the further step of washing the dewaxed specimen immediately after dewaxing with an aqueous wash composition comprising a detergent to remove residual dewaxing composition. Also provided is a kit for dewaxing a wax-embedded specimen, which comprises a dewaxing composition and can further comprise a second composition of (1) an immunostaining reagent or (2) an aqueous wash solution comprising a detergent for removing residual dewaxing solution.

Abstract:
An iron sulfide cleaning composition is described, along with a process for using the iron sulfide cleaning composition. The iron sulfide cleaning composition is simple to use and effective in removing deposits of iron sulfide from hydrocarbon wells. The iron sulfide cleaning composition consists of formaldehyde or glutaraldehyde, methanol, 2-butoxyethanol, isopropyl alcohol, hydrochloric acid, Surfactant Intermediate, Surfactant/Corrosion Inhibitor, glacial acetic acid and water.
Abstract:
A cleaning composition for treating and removing residue containing hydrocarbons and other flammable substances uses a mixture of one or more cleaning members containing quaternary salts, a chelator and a dispersant, mixed with water. The preferred cleaning members are tetradecyltrimethylammonium bromide, tetrasodium ethylenediaminetetraacetic acid, benzethonium hydrochloride and 2-butoxyethanol. The chelator is tetrasodium salt ethylenediamine of tetraacetic acid, and the dispersant is polyvinyl alcohol. Optionally, the cleaner contains ethanol and isopropyl alcohol.
