[0023] A nucleic acid remover, containing the following components and mass percentage: 10% hydrogen peroxide, 3% sodium hypochlorite, 3% oxalic acid, 2% acetic acid, 8% AEO-9, the rest is made up with deionized water, and the final pH value is adjusted 3.5.
Embodiment 3
[0025] Utilize the nucleic acid removal agent described in embodiment 1 and embodiment 2 to degrade the genome, the specific method is as follows:
[0026] (1) DNA / RNA genome extraction kit to extract nucleic acid
[0027] ①Take 0.2 g of pig liver sample, add 5 times the weight of normal saline, grind it evenly, add 20 μL of proteinase K solution, mix well, and lyse in a water bath at 56°C for 15 minutes;
[0028] ② Centrifuge at 12,000 rpm at room temperature for 5 minutes, take 200 μL of the supernatant and add it to a new centrifuge tube, then add 200 μL of buffer solution, mix thoroughly by inversion, and place at 70°C for 10 minutes;
[0029] ③ Add 200 μL of absolute ethanol, shake and mix well for 15 seconds;
[0030] ④ Add the above solution into an adsorption column, centrifuge at 12,000 rpm for 30 seconds, discard the waste liquid, and put the adsorption column back into the collection tube;
[0031] ⑤ Add 500 μL of washing solution to the adsorption column, centrif...
