Through a rapid and simple three-step process of binding, washing, and elution, 100 bp-10 kb DNA fragments can be purified and recovered from PCR products or enzyme reaction solutions (enzyme cutting, linking, probe labeling, etc.). Each adsorption column can adsorb up to 10 kb of DNA fragments µ G DNA, while minimizing impurities such as primers, oligonucleotides, enzymes, etc. The purified and recovered DNA has high purity and concentration, good integrity, and high recovery rate, and can be directly used for molecular biology experiments such as sequencing, linking and transformation, labeling, and in vitro transcription.Self prepared reagent: anhydrous ethanol.Preparation and important precautions before the experiment:1. 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. Column balance: Add 200 to the spin columns DM that have been loaded into the collection tube µ Centrifuge at 13000 rpm (~16200 × g) for 1 minute, discard the waste liquid in the collection tube, and place the adsorption column back into the collection tube.3. Add the solution obtained in step 1 to the adsorption column that has been loaded into the collection tube, let it stand at room temperature for 1 minute, centrifuge at 13000 rpm for 30-60 seconds, discard the waste liquid in the collection tube, and place the adsorption column in the collection tube.Attention: The volume of the adsorption column is 750 µ l. If the sample volume is greater than 750 µ l, it can be added in batches.4. Add 500 µ l of Buffer PW to the adsorption column (please check if anhydrous ethanol has been added before use), centrifuge at 13000 rpm for 30-60 seconds, discard the waste liquid in the collection tube, and place the adsorption column in the recovery tube.Note: If purified DNA is used for salt sensitivity experiments (such as flat end ligation experiments or direct sequencing), it is recommended to add Buffer PW and let it stand for 2-5 minutes before centrifugation.5.13000 rpm for 1 minute 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.). To ensure that downstream experiments are not affected by residual ethanol, it is recommended to open the cover of the adsorption column and place it at room temperature for a few minutes to thoroughly dry the residual ethanol in the adsorbent material at the bottom.6. Place the adsorption column into a new centrifuge tube (provided by oneself), add 30-50 µ l Buffer EB to the middle position of the adsorption membrane by hanging droplets, and let it stand at room temperature for 1 minute. Centrifuge at 13000 rpm for 1 minute and collect DNA solution- Store DNA at 20 ℃.Attention:1) 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 (the pH value of water can be adjusted to this range using NaOH).2) To improve the recovery of DNA, the solution obtained by centrifugation can be added back to the adsorption column, left at room temperature for 2 minutes, and centrifuged at 13000 rpm for 1 minute.3) The elution volume should not be less than 30 µ l. A small volume will affect the recovery efficiency... Read More | The content of this cell is too long for an XLSX file (more than 32767 characters).

The kit eliminates the need for phenol/chloroform extraction and is safe to handle. The extracted genomic DNA fragments are large, high purity, stable and reliable quality, suitable for PCR, fluorescence quantitative PCR, molecular labeling, library construction and other experiments.Self-contained reagent: anhydrous ethanolPre-experiment Preparation and Important Notes1. Repeated freezing and thawing of the sample should be avoided, as this may result in smaller fragments of extracted DNA and a decrease in the amount extracted.2. Anhydrous ethanol should be added to Buffer LP3 and Buffer GW2 according to the instructions on the label of the reagent bottle before first use. Check Buffer LP1 and Buffer LP2 for crystallization or precipitation before use. If crystallization or precipitation occurs, re-dissolve Buffer LP1 and Buffer LP2 in a 56°C water bath. Procedure1. Take about 100mg of fresh plant tissue or about 20mg of dry weight tissue and add liquid nitrogen to grind it fully.2. Collect the ground powder into a centrifuge tube (self-provided), add 400 µl Buffer LP1 and 6 µl RNase A (10 mg/ml), vortex and oscillate for 1 minute, and leave it at room temperature for 10 minutes to allow for full cleavage.Note: 1) Use vortex shaking or pipette blowing to fully lyses the tissue, incomplete tissue lysis will affect the final DNA yield. 2) Do not mix Buffer LP1 with RNase A prior to use.3. Add 130 µl Buffer LP2, mix well and vortex for 1 minute.4. Centrifuge at 12,000 rpm (~13,400 x g) for 5 minutes and transfer the supernatant to a new centrifuge tube (supplied).5. Add 1.5 times the volume of Buffer LP3 (check that anhydrous ethanol has been added before use) and mix thoroughly (e.g., 500 µl filtrate to 750 µl Buffer LP3).Note: Buffer LP3 should be mixed immediately after addition; precipitation may occur but will not affect subsequent experiments.6. Add all of the solution and precipitate obtained in the previous step to the adsorption columns (Spin Columns DM) that have been loaded into the collection tubes, if the solution cannot be added all at once, it can be transferred in several times. centrifuge the columns at 12,000 rpm for 1 minute, pour off the waste liquid in the collection tubes, and put the columns back into the collection tubes.7. Add 500 µl of Buffer GW2 to the adsorption column (check that anhydrous ethanol has been added before use), centrifuge at 12,000 rpm for 1 minute, pour off the waste liquid in the collection tube, and put the adsorption column back into the collection tube.Note: If the adsorbent membrane appears green, add 500 µl of anhydrous ethanol to the adsorbent column, centrifuge the column at 12,000 rpm for 1 minute, pour off the waste liquid in the collection tube, and put the adsorbent column back into the collection tube.8. Repeat step 7.9. Centrifuge at 12,000 rpm for 2 minutes and pour off the waste liquid in the collection tube. Leave the adsorption column at room temperature for several minutes to dry thoroughly.Note: The purpose of this step is to remove residual ethanol from the adsorption column, which can interfere with subsequent enzymatic reactions (digestion, PCR, etc.).10. Place the adsorption column in a new centrifuge tube (supplied), add 50-100 µl of Buffer GE or sterilized water dropwise to the middle of the adsorbent membrane, leave it at room temperature for 2-5 minutes, and centrifuge it at 12,000 rpm for 1 minute to collect the DNA solution. -The DNA solution was collected by centrifugation at 12,000 rpm for 1 min.Note: 1) If the downstream experiment is sensitive to pH or EDTA, you can use sterilized water for elution. The pH value of the eluent has a great influence on the elution efficiency, if you use water as the eluent, you should ensure that the pH value is 7.0-8.5 (you can use NaOH to adjust the pH value of the water to this range), and when the pH value is lower than 7.0, the elution efficiency is not high.2) Incubation at room temperature for 5 minutes prior to centrifugation increases yield.(3) If the final concentration of DNA is to be increased, the DNA eluate obtained in step 10 can be re-added to the adsorbent membrane and repeat step 10; if the elution volume is less than 100µl, the final concentration of DNA can be increased, but it may reduce the total DNA yield. If the amount of DNA obtained is less than 1µg, 50µl Buffer GE is recommended for elution.4) Because DNA stored in water is subject to acidic hydrolysis, for long-term storage, elution with Buffer GE and storage at -20°C are recommended...
