The invention discloses a method for rapid high-flux extraction of fungal genome DNA by glass bead grinding, and belongs to the technical field of molecular biology. According to the method, a CTAB method (cetyltrimethylammonium bromide method) is adopted, the required reagent is few, and expensive enzymes and other biochemical reagents do not need to be used. The method for extracting the DNA is low in cost, the whole method is easy to operate, the DNA extraction flux is high, and the needed time is short. The obtained genome DNA can be widely applied to experiments such as gene cloning, genotype detection and the like which require large-scale genome extraction.

The invention provides a gel electrophoresis kit which comprises the following components: concentrated gel which comprises 30% acrylamide / methylene bisacrylamide (29: 1) with the concentration of 5-30%; the photoinitiator is used for solidifying the liquid concentrated gel under the irradiation of a light source of 365 nm to 405 nm; the separation gel comprises the following components: 30% acrylamide / methylene bisacrylamide (29: 1) with the concentration of 10%-65%; the photoinitiator is used for solidifying the liquid separation gel under the irradiation of a light source of 365 nm to 405 nm; a concentrated gel buffer solution; and separating a gel buffer solution. The invention also provides a preparation method of the gel electrophoresis kit. According to the gel electrophoresis kit provided by the invention, the photoinitiator used when the separation gel and the concentration gel are prepared can be excited to generate photochemical change under the irradiation of a light source so as to generate an active intermediate with the capability of initiating polymerization, and the active intermediate can promote the solidification of liquid gel. The gel solidification speed under the excitation of the photoinitiator is obviously higher than that of natural solidification, and the experiment speed is accelerated.
