Embodiment Construction

[0072] Embodiment one: the making of the slide film that is used for comet experiment of the present invention

[0073] 1. The production material of the carrier film

[0074] 1. Ordinary glass slides (Sailboat brand glass slides, products of Jiangsu Feizhou Glass & Plastic Co., Ltd., specifications and models: length and width are 25.4mm×75.6mm, thickness is 1mm-1.2mm).

[0075] 2. Home improvement glass glue (Dow Corning brand, product of Shenzhen Zhenkun Chemical Co., Ltd., product model DC-7091)

[0076] 3. Glass knife (branded by Yangjiang Shibazi, product of Yangjiang Shibazi Group Co., Ltd.).

[0077] Second, the production method of the carrier film

[0078] 1. Along the short side of the glass slide, use a glass knife to cut into 3-4mm long thin strips,

[0079] 2. Use glass glue to stick the glass strips along the long axis of the glass slide. It is required to stick 4 strips for each slide, evenly spaced from each other and distributed in the middle of the slide....

Abstract

The invention provides a comet assay method for detecting DNA damage of earthworm coelomocytes. The method comprises production of simple glue carrying films and preparation of earthworm coelomocytes,can perform comet assay by only laying a layer of glue, and is simple, high in accuracy and high in efficiency.

Description

technical field [0001] The invention belongs to the field of cell detection, in particular to a method for detecting cell damage by using comet electrophoresis technology. Background technique [0002] Single cell gel electrophoresis (single cell gel electrophoresis Assay, SCGE), also known as Comet Assay, was invented by Ostlingn in 1984 and is a technique for detecting DNA damage in eukaryotic cells. Currently, it is used in genotoxicity tests and environmental pollution tests It has a wide range of applications related to the basic research fields of molecular epidemiology, ecopathology and DNA damage repair. The principle is: lyse the cells embedded in agarose, and then unwind and electrophoresis the DNA. If the cellular DNA breaks into pieces, comet-like structures can be seen under the microscope after staining. The main experimental steps include: preparation of single cell suspension, gel preparation and spreading, lysis, unwinding, electrophoresis, neutralization,...
