Abstract

The invention relates to an adhesive, which is mainly applied to pathological and biological analysis, and is used for prompting the adhesion and adherence of various cell types and biological tissues on glass slides and various vessels. The adhesive is formulated by the following component in percentage by weight of 10-15% of ethylene-butadiene dimethyl ammonium chloride-acrylamide copolymer, 10-15% of dimethyl siloxane, 0.8-2% of dodecyl trimethyl ammonium chloride, 0.4-0.8% of EDTA (Ethylene Diamine Tetraacetic Acid), 41-55% of ethanol and 20-30% of pure water. The invention aims to provide the adhesive for solving the defects in the background technology, so that the problems in the prior art of high cost, environmental pollution, short expiration date, and fitness of temporary use in a lab can be solved; and the purposes of stable and efficient property, low cost, environmental friendless and harmlessness, long product expiration date and fitness of industrial scale production can be achieved.

Description

technical field [0001] The present invention relates to an adhesive, which is mainly used in pathological and biological examinations to promote the adhesion and wall attachment of various cell types and biological tissues on glass slides and various utensils. Background technique [0002] Tissue slices and slide adhesives (slide adhesives) in the prior art generally adopt materials such as polylysine, APES (3-aminopropyl-3-ethoxysilane), and are processed by Materials such as glass slides and utensils are coated, so that the surface of the glass slide or other utensils forms a layer of coating that has the ability to adsorb or adhere to biological tissues or cells. [0003] Polylysine solution is a widely used adhesive for tissue slices and glass slides, and the polycation molecules interact with anions on tissue slices to produce strong adhesive force. Commonly used poly-lysine coating can be used triple distilled water or PBS, the concentration is generally 0.1mg / ml, per...
