Adhesive composition for coating of glass slide and single-surface coating technology

Abstract

The invention relates to an adhesive composition for coating of a glass slide and a single-surface coating technology. The adhesive composition is prepared from the following components according to amass / volume ratio: a component 1 and a component 2, wherein the component 1 is prepared from 0.05 to 0.3% of film forming agent (polyvinyl alcohol), 0.02 to 0.25% of adhesive (carboxymethylcellulose), and the balance of water; the component 2 is prepared from 0.2 to 1mg / 100ml of cationic swelling agent (polylysine), and the balance of water. The single-surface coating technology comprises the following steps of cleaning the glass slide by ultrasonic waves in an alkaline solution, drying, spraying and coating the component 1 to the front surface according to the amount of 20 to 50mu l per piece, drying at the temperature of 35 to 55 DEG C, cooling to room temperature, spraying and coating the component 2 to the same surface according to the amount of 10 to 30mu l per piece, drying at the temperature of 35 to 55 DEG C, and packaging under the vacuum condition. The adhesive composition has the advantages that the effects of high adhesivity, uniform distribution and high definition of cells or tissues on the glass slide are realized; the continuous, automatic, stable, uniform and batch type single-surface zonal spraying and coating technology is realized. The prepared pathology slidecan resist the repeated washing and soaking by various alcohols and reagents, be suitable for the wall attaching, single-layer distribution and no falling of the cells, the tissues and the like, and can reach the effects of clear background and no impurity.

Description

technical field [0001] The invention relates to an adhesive composition and an adhesive coating process for improving cell or tissue adhesion and high definition of pathological glass slides, in particular to a glass slide adhesive composition and an adhesive coating process. Its preparation method, and the preparation method of the coating process on the glass slide. Background technique [0002] In clinical pathology, tissue slices and liquid-based thin-layer cells are widely used in cytomorphological examination. Thin-layer cell slices and tissue slices are used to achieve the application of cell / histological examination of corresponding diseases and identification of clinical lesions has become increasingly common. In terms of pathological examination, the systemic and in-depth research on the adhesion and detachment resistance of cell thin layers or tissue sections to glass slides is not very extensive or in-depth, but adhesion to slides or detachment prevention The p...
