Attention: The DNA production has reached its maximum after 10 minutes of incubation, and further extension of incubation time has no effect on DNA production and purity.5. Add 200 µ L anhydrous ethanol, invert and mix several times. Short centrifugation causes the liquid on the tube wall and wall cover to concentrate at the bottom of the tube.6. Add all the solution obtained in step 5 to the spin columns DM that have been loaded into the collection tube. If the solution cannot be added at once, it can be transferred multiple times. Centrifuge at 12000 rpm for 1 minute, discard the waste liquid in the collection tube, and place the adsorption column back into the collection tube.7. Add 500 to the adsorption column µ L Buffer GW1 (check if anhydrous ethanol is added before use), centrifuge at 12000 rpm for 1 minute, discard the waste liquid in the collection tube, and place the adsorption column back into the collection tube. Note: If the extracted sample is the blood genome of species such as mice or monkeys that are difficult to remove heme, it is recommended to repeat step 7.8. Add 500 to the adsorption column µ L Buffer GW2 (check if anhydrous ethanol is added before use), centrifuge at 12000 rpm for 1 minute, discard the waste liquid in the collection tube, and place the adsorption column back into the collection tube. Note: To further improve DNA purity, repeat step 8.9.Centrifuge at 9.12000 rpm for 2 minutes and discard the waste liquid from the collection tube. Place the adsorption column at room temperature for a few minutes to thoroughly air dry. Note: The purpose of this step is to remove residual ethanol from the adsorption column, which can affect subsequent enzymatic reactions (such as enzyme digestion, PCR, etc.)10. Place the adsorption column in a new centrifuge tube (provided by oneself) and add 50-200 to the middle of the adsorption column in the air µ L Buffer GE or sterilized water, leave at room temperature for 2-5 minutes, centrifuge at 12000 rpm for 1 minute, collect DNA solution, and store DNA at -20 ℃. Note: 1) If downstream experiments are sensitive to pH or EDTA, they can be washed off with sterilized water. The pH value of the eluent has a significant impact on the elution efficiency. If water is used as the eluent, its pH value should be ensured to be between 7.0-8.5 (NaOH can be used to adjust the pH value of the water to this range). When the pH value is below 7.0, the elution efficiency is not high. 2) If the final concentration of DNA needs to be increased, the obtained DNA eluent can be added back to the adsorption membrane, left at room temperature for 2-5 minutes, and centrifuged at 12000 rpm for 1 minute. 3) Because DNA stored in water is affected by acidic hydrolysis, if long-term storage is required, it is recommended to elute with Buffer GE and store at -20 ℃...

All components can be stably stored in a dry, room temperature (15-30 ℃) environment for 1 year, and can be stored at 2-8 ℃ for longer periods of time. When the solution is stored at low temperature, it should be left at room temperature for a period of time before use, and then restored to room temperature before use.2. This reagent kit can selectively recover all DNA fragments from the solution. If you need to selectively recover specific fragments while removing other fragments of different sizes, please choose our company's gel recovery reagent kit.3.Before the first use, anhydrous ethanol should be added to the Buffer PW according to the instructions on the reagent bottle label.4. Before use, please check if there is any crystallization or precipitation in the Buffer PB. If there is any crystallization or precipitation, you can take a water bath at 37 ℃ for a few minutes to restore clarity.5. The recovery efficiency is related to the initial amount of DNA and the elution volume. The smaller the initial amount, the smaller the elution volume, and the lower the recovery rate.6. All centrifugation steps can be performed at room temperature.Operation steps:1. Estimate the volume of DNA reaction solution, add 5 times the volume of Buffer PB, and mix thoroughly (without removing paraffin or mineral oil).Note: 1) If the DNA reaction system is 50 µ l (excluding paraffin oil volume), add 250 µ l Buffer PB.2) After adding Buffer PB, check the pH value of the solution. If the pH value is greater than 7.5, add 10-30 to it µ 3 M sodium acetate (pH 5.0) was used to adjust the pH value to 5-7.2.
