We applied the iHE method to stain intact organs of mice, which were then sectioned and imaged sequentially. [4] For example, when a pathologist looks at a biopsy of a suspected cancer, the histological section is likely to be stained with H&E. 1C-III, we also found that encephalocele of the brain with ultrasound and delipidation was larger than that of the brain without ultrasound and delipidation, possibly due to the shrinkage of the brain during dehydration and delipidation. Therefore it stains the basic structures of a cell (acidophils), giving them a red or pink color, for example, the cytoplasm is positively charged, and therefore it will take up the eosin dye, and appear pink. Another benefit is whetherlaboratories prefer progressive (more consistent results) or regressive staining. Extreme Sheen on the surface and slides will have a distinct blue/black coating over the entire slide. (M. Nijhoff Publishers; Distributors for the U.S. and Canada, Kluwer Boston, 1982).
