Abstract

The invention discloses a hematoxylin-eosin rapid staining solution and an application method thereof, which belong to the technical field of biology. Specifically speaking, the hematoxylin-eosin rapid staining solution is prepared from an improved hematoxylin staining solution and a novel eosin staining solution. The hematoxylin-eosin rapid staining solution provided by the invention is easy to operate, staining is uniform, a stained cellular structure is clear, cell coloration is vivid, and clinical pathological diagnosis, observation and judgment are facilitated.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a rapid hematoxylin-eosin staining solution, and simultaneously the invention also relates to an application method of the staining solution. Background technique [0002] Hematoxylin-eosin staining, referred to as HE staining, is the most common and widely used conventional staining method for pathological tissue sections. Hematoxylin is easily oxidized, and its oxidation product hematoxylin is the real fuel. It is customary to say that hematoxylin is a basic dye, but in fact hematoxylin is an acid dye, and only a positively charged blue color essence formed by hematoxylin and aluminum is alkaline. The combination of the positively charged blue color essence and the nucleus is accomplished through the polar adsorption of positive and negative charges, that is to say, the negatively charged deoxyribose nucleic acid root and the positively charged blue color essence are completed by ...
