Abstract
A cytological fixative and dehydrating agent used for treating histological and cytological tissues for pathological diagnoses consists of a blend of from about 11 to 21% ethyl alcohol, from about 35 to 45% methyl alcohol and from about 40 to 50% by weight isopropyl alcohol. The treated tissue is subjected to further processing to render the cells in the tissue stable prior to placing the tissue upon a glass slide for pathological examination.
