摘要:
The invention is directed to methods and compositions for deparaffinizing paraffin-embedded biological samples for subsequent tissue staining. The compositions are microemulsions that may include water/oil/surfactant microemulsions, and optionally a cosurfactant. The microemulsions enable deparaffinization without the use of xylene or toluene, and also enable solvent exchange without the use of intermediary alcohol dehydration or alcohol rehydration compositions.

摘要:
A platen for contacting a liquid to a surface of a substantially flat substrate is disclosed. The platen includes a liquid application station and a stripping element at an end of the liquid application station, wherein the stripping element includes an intersecting gap and an air barrier. Also disclosed are an apparatus including the platen and a method of using the platen to contact a substrate with a liquid.
摘要:
A method and apparatus for treating a biological sample with a liquid reagent, comprising first and second substrates having facing surfaces defining a space therebetween in which the biological sample may be treated with the liquid reagent, wherein the first substrate comprises a relatively rigid fluid impermeable element while the second substrate comprises a relatively flexible liquid impermeable element.
摘要:
The present invention is directed to materials that assist respiration of living cells contained in cell-containing systems. The materials form air-filled conduits or channels through which gases, such as oxygen and carbon dioxide, can readily exchange by diffusional means between regions of different gas partial pressures. When the present invention is placed within an aqueous environment, such as cell-culture media or host tissue, the invention provides aid to cellular respiration in cell-containing systems.
摘要:
A method and apparatus for thin film fluid processing of biological samples without rinsing between treatments is provided. An apparatus having a treatment zone for treating a biological sample with a liquid reagent, comprising first and second substrates having facing surfaces defining a space therebetween in which the biological sample may be treated with the liquid reagent, wherein the first substrate comprises a relatively fluid impermeable element while the second substrate comprises a relatively flexible gas permeable element.
