The present invention provides reagents for use in an automated environment for cell conditioning of biological samples wherein the cells or tissues are predisposed for access by reagent molecules for histochemical and cytochemical staining procedures. The components of the reagents are optimized to facilitate molecular access to cells and cell constituents within the biological sample. The present invention also provides reagents for use in an automated environment for removing or etching embedding media by exposing a biological sample to be stained in histochemical or cytochemical procedures without the dependence on organic solvents. The components of the reagents are optimized to facilitate removal or etching of the embedding media from the biological sample.
An aqueous composition of matter, comprising citrate buffer, ethylene glycol, sodium metabisulfite and sodium dodecyl sulfate (SDS).
An aqueous composition of matter comprising a buffer, a glycol, sodium metabisulfite and sodium dodecyl sulfate.
An aqueous composition of matter comprising approximately 10 mM citrate buffer at approximately pH 6, approximately 5% ethylene glycol, approximately 1 mM sodium metabisulfite and approximately 0.3% SDS.
