Anhydrous ethanol should be added to Buffer GW1 and Buffer GW2 according to theinstructions on the label of the reagent bottle before first use.5. Please check Buffer GL for crystallization or precipitation before use, if thereis any crystallization or precipitation, please put it in 56℃water bath to re-dissolve.6. If the downstream experiments are sensitive to RNA contamination, 4µl of DNaseFree RNase A (100mg/ml) can be added, RNase A is not provided in the kit, and canbe ordered separately from our company if needed.7. The Buffer RCL in the kit cannot be used further after turbidity.procedure1. Add 1-5 ml of blood sample to a centrifuge tube (supplied) and add 3 times thevolume of Buffer RCL and gently vortex or invert to mix.2. Centrifuge at 3000 rpm (~900 x g) for 10 minutes and carefully aspirate thesupernatant.3. Add 400 µl Buffer GR to the precipitate and resuspend the precipitate. Note: If the downstream assay is sensitive to RNA, add 4 µl of RNase A (100 mg/ml)solution, shake for 15 seconds, and leave at room temperature for 5 minutes.4. For 1-2 ml blood sample extraction, add 40µl Proteinase K to the above solutionand mix well; for 2-5 ml blood sample extraction, add 100µl Proteinase K to theabove solution and mix well.5. Add 400 µl of Buffer GL, mix upside down 15 times, and vigorously vortex andshake for at least 1 minute. Note: Do not add Proteinase K directly to Buffer GL.6. Incubate at 70°C for 10 minutes, during which time mixing was inverted severaltimes.Note: 1) If the solution is not completely clear, add appropriate amount of Proteinase K and incubate. Extend the incubation time until the solution is completely clear. 2) The yield of DNA has been maximized by 10 minutes of incubation, and continuedprolongation of the incubation time has no effect on DNA yield or purity.7. Add 400 µl of anhydrous ethanol and mix upside down 10 times. Centrifuge brieflyto concentrate the liquid on the walls and cap to the bottom of the tube.8. Add all of the solution obtained in the previous step to the Spin Columns DL inthe collection tube. If the solution cannot be added all at once, transfer it severaltimes. centrifuge at 12,000 rpm (~13,400 x g) for 1 minute, pour off the waste liquidfrom the collection tube, and put the column back into the collection tube.9. Add 500 µl of Buffer GW1 to the adsorption column (check that anhydrous ethanolis added before use), centrifuge at 12,000 rpm for 1 minute, pour off the waste liquidin the collection tube, and put the adsorption column back into the collection tube.Note: It is recommended that step 9 be repeated if the sample being extracted isthe blood genome of a species such as mice or monkeys from which hemoglobin isdifficult to remove.10. Add 500 µl Buffer GW2 to the adsorption column (check that anhydrous ethanolis added before use), centrifuge at 12,000 rpm for 1 minute, pour off the waste liquidin the collection tube, and put the adsorption column back into the collection tube.Note: Step 10 can be repeated if further DNA purity is required.11. Centrifuge at 12,000 rpm for 2 minutes and pour off the waste liquid in thecollection tube. Leave the adsorption column at room temperature for several minutesto dry thoroughly. Note: The purpose of this step is to remove residual ethanol from the adsorptioncolumn, which can interfere with subsequent enzymatic reactions (digestion, PCR,etc.)12. Place the adsorption column in a new centrifuge tube, add 50-200 µl of BufferGE or sterilized water to the middle of the adsorption column overhanging the column,leave it at room temperature for 2-5 minutes, centrifuge at 12,000 rpm for 1 minute,collect the DNA solution, and store the DNA at -20℃.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 theelution efficiency, if water is used as the eluent should ensure that its pH is7.0-8.5 (you can use NaOH to adjust the pH of the water to this range), and the elutionefficiency is not high when the pH is lower than 7.0.2) Incubation at room temperature for 5 minutes prior to centrifugation increasesyield.3) Re-elution with an additional 50-200 µl Buffer GE or sterilized water can increase the yield.4) If the final concentration of DNA is to be increased, the DNA eluate obtainedin step 12 can be re-spiked onto the adsorbent membrane and centrifuged at 12,000rpm. 1min; if the elution volume is less than 200µl, the final concentration of DNA canbe increased, but the total yield may be reduced. If the amount of DNA is less than1 µg, elution with 50 µl Buffer GE or sterilized water is recommended.5) Because DNA preserved in water is subject to acidic hydrolysis, for long-termstorage, it is recommended that it be eluted with Buffer GE and stored at -20℃...

The optimized buffer system enables the DNA in the lysate to specifically bind to the adsorbent membrane, and the inhibitor is effectively removed by a two-step rinsing step, and finally eluted with low-salt buffer or water to obtain high-purity DNA.Meanwhile, configured with a high-efficiency microsorbent column, the elution volume can be as low as 20 µL.The purified DNA can be directly used for PCR, Real-time PCR, SNP Genotyping, STR genotyping, second-generation sequencing and pharmacogenomics research.The molecular weight of DNA isolated from formalin-fixed, paraffin-embedded samples is usually lower than that of DNA from fresh or frozen samples.The degree of DNA fragmentation depends on the type of sample, the duration of storage, and the conditions of fixation.Self-contained reagent: anhydrous ethanolPre-experiment Preparation and Important Notes1. After obtaining the sample, fix the sample in 4%-10% formalin as soon as possible, the fixation time should be 14-24 hours, too long a period of time will easily lead to genome breakage, affecting the downstream experiments. If the formaldehyde fixation time is too long or the sample has been stored for too long (> 1 year), it will easily lead to DNA integrity damage and unable to amplify long fragments.2. Ensure that the sample is thoroughly dehydrated before embedding; residual formalin will inhibit Proteinase K.3. 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.4. Before use, please check Buffer GTL, Buffer GL and Buffer DS for any crystallization or precipitation. If there is any crystallization or precipitation, please re-dissolve Buffer GTL, Buffer GL and Buffer DS at 56℃ in a water bath.5. Preheat the water bath or thermostatic mixer to 56°C and keep the centrifuge at 25°C before starting the experiment.6. If downstream experiments are needed to reduce the low frequency of C>T:G>A transitions (artificial mutations) that occur to minimize the risk of false positives, 7 µL of UNG (1 U/uL) can be added after 1 hour of incubation at 90°C.Operation steps1. Sample processing:1a. Paraffin-embedded samples: Trim off excess paraffin from the tissue block with a scalpel to expose the tissue and then cut into 5-10µm slices. Take about 1×1cm2 slices (about 4-5 slices in total) and place them in a centrifuge tube (provided), add 160µL Buffer DS, vortex and shake for 10 seconds, then add 180µL Buffer GTL and 20µL Proteinase K, vortex and shake for 10 seconds. centrifuge the samples at 12,000rpm for 1 minute at 25℃.Note: 1) If the surface of the sample has been exposed to air, discard the 2-3 pieces that have been exposed to air and do not use them.2) DS will solidify below 18°C, and if it does it does not affect the following experiments.1b. Sample in formalin and other fixative: take about 20mg of sample, cut it into small pieces, place it in a centrifuge tube, add 500µL of 10mM PBS (PH7.4), vortex shaking, centrifuge at 12,000rpm for 1minute, discard the supernatant, and repeat 3 times. Add 180 µL Buffer GTL, 20 µL Proteinase K, vortex shaking to mix.2.56°C for 1 hour until the sample is completely dissolved. incubate at 90°C for 1 hour. centrifuge at 12,000 rpm, 25°C for 1 minute, and carefully pipette the lower aqueous phase (~180 µL) along the wall of the tube into a new centrifuge tube, trying to avoid aspirating the bottom precipitate and the upper layer of the wax solution.Note: 1) Samples can be left at room temperature after incubation at 56°C until the temperature of the water or dry bath reaches 90°C before placing the samples at 90°CIncubation.2) Optional step: add 7µL UNG (1U/µL), 50°C, 5min, no shaking. The purpose of this step is to minimize the risk of false positives by reducing the low-frequency occurrence of C>T:G>A transitions (artificial mutations) while effectively retaining the true occurrence of mutations.3. Optional step: If you need to remove RNA, you can lower the temperature of the sample to room temperature, then add 2µL of RNase A solution at a concentration of 100mg/mL, shake and mix well, and leave it at room temperature for 2 minutes.4. Add 20µL Proteinase K and incubate at 65℃, 450rpm for 15min.5. Add 200 µL of Buffer GL, mix well by vortexing and shaking, then add 200 µL of anhydrous ethanol and mix thoroughly by vortexing and shaking. Centrifuge briefly so that the solution on the wall of the tube collects at the bottom of the tube.Note: 1) Mix well immediately after adding Buffer GL and anhydrous ethanol.2) The addition of Buffer GL and anhydrous ethanol may produce a white precipitate that will not affect subsequent experiments.3) If more than one sample needs to be manipulated, the Buffer GL and anhydrous ethanol can be pre-mixed and spiked.6. Add all the solution obtained in step 5 to the adsorption columns (Spin Columns DF) that have been loaded into the collection tube, centrifuge at 25℃, 12000rpm for 2 minutes, pour out the waste liquid in the collection tube, and put the adsorption columns back into the collection tube.7. Add 500µL of Buffer GW1 to the adsorption column (check that anhydrous ethanol has been added before use), centrifuge at 12,000rpm for 1 minute, pour off the waste liquid in the collection tube, and put the adsorption column back into the collection tube.8. Add 500µL of Buffer GW2 to the adsorption column (check that anhydrous ethanol has been added before use), centrifuge at 12000rpm for 1 minute, pour off the waste liquid in the collection tube, and put the adsorption column back into the collection tube.Note: Step 8 can be repeated if further DNA purity is required.9.12 Centrifuge at 2000 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; ethanol residue can interfere with subsequent enzymatic reactions.10. Place the adsorption column in a new 1.5 mL collection tube, add 20-100 µL of Buffer TE or sterilized water to the middle of the adsorption column overhanging the column, let it stand at room temperature for 2-5 minutes, centrifuge it at 12,000 rpm for 1 minute, and collect the DNA solution.-20°C to preserve DNA.Note: 1) The pH value of the eluent has a great influence on the elution efficiency, if water is used as the eluent should ensure that its pH value is 7.0-8.5, the pH value is lower than 7.0 when the elution efficiency is not high.2) If the final concentration of DNA is to be increased, the DNA eluate obtained in step 10 can be re-spiked onto the adsorbent membrane and left at room temperature for 2 minutes and centrifuged at 12,000 rpm for 1 minute...
