Abstract

The invention discloses an epithelial tissue staining reagent. The epithelial tissue staining reagent comprises components in percentage by weight as follows: 0.5%-15% of folic acid derivatives, 0.02%-10% of methylene blue, 0.1%-5% of horseradish peroxidase, 2%-10% of aminogalactose, 2%-10% of N-phthaloyl chitosan oligosaccharide, 2%-6% of medical glacial acetic acid and the balance of deionized water, wherein the folic acid derivatives preferably adopt one or more of 5,6,7,8-tetrahydrofolic acid, histidine N-acetyl-2-ethanediamide folic acid and cysteamine modified folic acid. The epithelial tissue staining reagent has the advantages as follows: the raw materials don't have irritation to skin and tract mucosa; the specificity is better; the selected folic acid derivatives are more easily combined with a folic acid receptor; saccharide derivatives have good reducibility and good solubility and are easy to prepare.

Description

technical field [0001] The present invention relates to a dye composition for epithelial tissue, especially tumor tissue, and also to a preparation method of the dye. Background technique [0002] In recent years, the morbidity and mortality of malignant tumors are very high, and the mortality is closely related to early diagnosis and treatment. How to diagnose and treat early is a hot research topic in the medical field in recent years. Currently, malignant tumors are mainly confirmed by pathological cytological examination and histological examination, which are diagnosed by changes in cell morphology and tissue structure. However, the cells of patients with early malignant tumors often only show an increase in nucleic acid that is difficult to diagnose, and there is no change in morphology and structure, which is the main reason for the missed diagnosis of cytology and histology. At present, the staining and detection technology for tumor cells has developed rapidly. The...
