The optimized buffer system enables DNA to bind heterogeneously to the silica matrix centrifugal adsorption column, and the inhibitors of PCR and other enzymatic reactions can be effectively removed by a two-step washing step, and finally eluted with a low-salt buffer or water to obtain high-purity DNA.The purified obtained can be directly used for enzyme digestion, PCR, Real-Time PCR, library construction, Southern Blot, molecular labeling and other downstream 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 GW1 and Buffer GW2 according to the instructions on the label of the reagent bottle before first use.3. Before use, please check whether Buffer GL appears to be crystallized or precipitated.Redissolve in a 56°C water bath.4. If the downstream experiments are sensitive to RNA contamination, 4 µL DNase-Free RNase A can be added in step 3(100 mg/mL).5. For prolonged storage of salivary DNA at room temperature, our Salivary DNA Preservation Tubes are recommended.Operation steps1. Add 400 µL of saliva sample or saliva/preservation solution mixture.Note: 1) Saliva mixtures added to the preservation solution require a 50°C water bath for 1 hour or an empty 50°C temperature chamber for 2 hours prior to extraction.2) If an increase in sample volume is required, multiply the volumes of Proteinase K, Buffer GL, and anhydrous ethanol in Steps 2-4, and the liquid can be transferred in multiple times in Step 5.2. Add 40 µL of Proteinase K.3. Add 400µL Buffer GL, vortex and shake to mix thoroughly, and water bath at 56℃ for 15-30 minutes.Note: If RNA removal is required, add 4 µL of RNase A solution at a concentration of 100 mg/mL after the above steps are completed, vortex for 15 seconds, and leave at room temperature for 2 minutes.4. Centrifuge briefly to remove water droplets from the inside of the tube cap. Add 400 µL of anhydrous ethanol and mix well by vortexing and shaking. Centrifuge briefly.Note: 1) Vortex and shake to mix immediately after adding Buffer GL and anhydrous ethanol.The addition of Buffer GL and anhydrous ethanol may produce a white precipitate that will not affect subsequent experiments.2) A sol-gel product may be formed after GL and anhydrous ethanol, in which case vigorous shaking or vortexing is recommended.3) The solution obtained in the previous step is added to the adsorption column in the Collection Tube.5. (Spin Column DM) in the collection tube, and if the solution cannot be added all at once, it can be transferred in several times. centrifuge at 12,000 rpm (∼13,400 × g) for 1 min, pour off the waste solution in the collection tube, and put the adsorption column back into the collection tube.6. Add 500 µL of Buffer GW1 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.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: Step 7 can be repeated if further DNA purity is required.8. 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.).9. Place the adsorption column in a new centrifuge tube (supplied), add 50-200 µL of Buffer GE or sterilized water to the middle of the adsorption column overhanging the column, let it stand at room temperature for 2-5 minutes, and centrifuge at 12,000 rpm for 1 minute to collect the DNA solution.-20°C to preserve DNA.Note: 1) If the downstream experiment is sensitive to pH or EDTA, you can use sterilized water for elution. The pH of the eluent has a great influence on the elution efficiency, if water is used as the eluent should ensure that its pH is 7.0-8.5 (you can use NaOH to adjust the pH of the water to this range), and the elution efficiency is not high when the pH is lower than 7.0.2) Buffer GE preheated in a 65-70°C water bath and incubated at room temperature for 5 min before centrifugation can increase the yield.3) Because DNA preserved in water is subject to acidic hydrolysis, for long-term storage, elution with Buffer GE and storage at -20°C is recommended...
