6. Dyeing and dyeing method is commonly used Fengpian hematoxylin - eosin (Hematoxylin-Eosin) staining biopsy, referred HE staining. This method of organization and application of any fixative embedding fixed slices can be used. Hematoxylin is a basic dye, allow tissue stained blue basophilic material, such as nuclear chromatin, etc; eosin is an acidic dye, make tissue stained red eosinophilic material Henan Slice cases, as the majority of the cytoplasm, nucleolus and other HE staining showed red slices. HE staining procedures are as follows: dewaxing, from benzene, rehydration, staining, dehydration, transparent, cementing routine hematoxylin staining in comparison with eosin staining, some laboratories in Britain in recent years, the United States and countries in the use of flame red ( phloxine), in addition it also uses orange G (OrangeG), Biebrich, Rhineland Palatinate scarlet (Biebrich scarlet), Bordeaux (Bordeaux red), etc., as contrast dye. Eosin dye used for staining cytoplasm, collagen fibers, muscle fibers, eosinophilic particles. (5) the thickness of the slice: the slicer thickness regulator engraved 0 ~ 50μm or 0 ~ 25μm, the thickness thereof can be arbitrarily selected, paraffin slice thickness is generally 4 ~ 6μm. (6) sections (7) stretched: ophthalmic tweezers tweezers with wax on the surface with a lightly tile 40 ~ 45 ℃ tissue biopsy, by the tension of the water and the water temperature will be slightly wrinkled wax with natural exhibition level. (8) patch, baking sheet: After slicing the water on the heated sufficiently flattened middle groan at the wax to pour over the water slides on the slide, placed in an oven at 60 ~ 65 ℃ or within slice drift bake oven temperature controller chip bake 15 to 30 minutes, removing melted paraffin tissue space.
