Problems solved by technology

[0012] After long-term use, people found that the existing hematoxylin staining solution also has the following defects: 1) It is easy to produce metal film and dye precipitation, thereby contaminating the slices, and in the process of making slices, the above-mentioned stains on the slices are difficult to remove, resulting in Inhomogeneous staining, or even unreadable slides, need to be re-made; 2) False blue staining is prone to occur during the staining stage, and part of ...

Abstract

The invention provides a hematoxylin staining solution which comprises the following components of hematoxylin, aluminium salt, an oxidizing agent, benzalkonium chloride, alcohol, weak acid and water. The invention further provides a preparation method of the hematoxylin staining solution, a HE (hematoxylin eosin) staining solution containing the hematoxylin staining solution, and a staining method. When the hematoxylin staining solution is used to stain a section, the background of the section is clear, the section is well arranged, the staining effect is excellent, the section is easy to read, the color of the section does not fade easily, and the section can be stored conveniently for a long period of time.

Description

technical field [0001] The invention relates to an in vitro diagnostic reagent, in particular to a hematoxylin staining solution and a preparation method thereof, as well as an HE staining solution containing the hematoxylin staining solution and a staining method thereof. Background technique [0002] Hematoxylin and eosin staining, referred to as HE staining, is the most widely used technique in histology, embryology, and pathology. HE staining is to immerse tissue sections or cell smears in hematoxylin staining solution and eosin staining solution respectively, and after appropriate time and treatment, the tissues, cells and other components are stained with different shades of color, resulting in different refractive indices. It is convenient for observation and research under an optical microscope. [0003] Hematoxylin is a kind of basic dye, which is extracted from logan and is oxidized to generate hematin. It is used together with mordant to make the chromatin in the...
