Abstract

The invention belongs to a routine dyeing reagent for a routine pathological section making and a use method of the routine dyeing reagent, and discloses a hematoxylin-eosin one-step dyeing method. The hematoxylin-eosin one-step dyeing method disclosed by the invention is characterized by comprising the following steps: preparing a hematoxylin-eosin one-step dyeing solution and a specific pH value buffer solution so that hematoxylin dyeing and eosin dyeing are completed in one step without the steps of differentiating and turning blue, and rinsing the sections with the specific pH value buffer solution before and after dyeing. According to the hematoxylin-eosin one-step dyeing method disclosed by the invention, one-step dyeing of cytoplasm and nucleus can be achieved, the operation steps are simplified and the operation time is shortened; the hematoxylin-eosin one-step dyeing method is good in dyeing effects and stable in results, is suitable for dyeing of routine formalin fixation and paraffin-embedded tissue sections, and can also be used for dyeing of frozen tissue sections or cultured cells, and favorable conditions are provided for rapid and accurate clinical pathological diagnosis.

Description

technical field

[0001] The invention relates to a hematoxylin-eosin staining solution and a staining method thereof, which belong to conventional staining reagents for routine pathological film production and methods for using the reagents. Background technique

[0002] Hematoxylin-eosin staining (HE staining for short) is the most basic and important staining method in routine pathological slide preparation, and is widely used clinically. Hematoxylin is a basic dye that can stain the nucleus blue; eosin is an acid dye that can stain the cytoplasm red. In pathological diagnosis, teaching and scientific research, HE staining is often used to observe the morphology and structure of normal and diseased tissues. To determine or identify certain abnormal substances and special components in diseased tissues and cells, special staining methods, enzyme histochemical methods or immunohistochemical methods are required, which are also based on the observation of HE-stained tissue se...
