The optimized buffer system enables the nucleic acids in the lysate to bind specifically to the adsorbent membrane, and the inhibitors are effectively removed by a two-step rinsing step, and finally eluted with low-salt buffer or water to obtain high purity DNA and RNA, and at the same time, equipped with a high-efficiency microsorbent column, the volume of the elution can be as low as 20 µl. The purified DNA and RNA can be directly used for PCR, Real-time PCR, SNP genotyping, STR genotyping, and so on. The purified DNA and RNA can be directly used for PCR, Real-time PCR, SNP genotyping, STR genotyping, second-generation sequencing, pharmacogenomics research and blot analysis.Self-contained reagent: anhydrous ethanolPre-experiment Preparation and Important Notes 1. After obtaining the sample, fix the sample as soon as possible, the fixation time of 14-24 hours is appropriate, too long a period of time will easily lead toDNA and RNA breaks, affecting downstream experiments. If the formaldehyde fixation time is too long or the sample is stored for too long(>1 year) is prone to compromise DNA integrity and failure to amplify long fragments.2. Ensure that samples are thoroughly dehydrated prior to embedding; residual formalin will inhibit Proteinase K action.3. Add 1.25 ml of Proteinase K Storage Buffer to Proteinase K to dissolve it, and store at -20℃. Do not leave the prepared Proteinase K at room temperature for a long period of time to avoid affecting its activity.4. Anhydrous ethanol should be added to Buffer RW2, Buffer GW1 and Buffer GW2 according to the label instructions on the vials before first use.5. Check Buffer GTL, Buffer GL and Buffer DS for crystallization or precipitation prior to use; if crystallization or precipitation occurs, redissolve Buffer GTL, Buffer GL and Buffer DS in a 37°C water bath.6. Preheat the water bath or thermostatic mixer to 56°C before starting the experiment.7. Use an ambient temperature centrifuge or set the centrifuge temperature to 25°C. Temperatures below 15°C may result in clogging of the adsorption column.8. To prevent RNase contamination, the following should be observed:1) Use RNase-free plastics and tips to avoid cross-contamination.(2) Glassware should be dry baked at 180°C for 4 hours before use, plasticware can be soaked in 0.5 M NaOH for 10 minutes, rinsed thoroughly with water and autoclaved.3) RNase-free water should be used to prepare the solution.(4) Operators wear disposable masks and gloves, and change gloves diligently during the experiment.procedureParaffin-embedded samples1. Trim off excess paraffin from the tissue block to expose the tissue and cut into 5-10 µm slices.2. Place approximately 1 x 1 cm2 slices (1-5 slices in total) in a centrifuge tube (supplied), add 500 µl of Buffer DS and vortex for 10 s. Briefly centrifuge the sample to the bottom of the tube. Centrifuge briefly to collect the sample at the bottom of the tube, incubate at 56°C for 3 minutes, remove from the water bath and allow to cool to room temperature before proceeding.Note: If the surface of the sample is exposed to air, discard the initial 2-3 slices without using them.3. Centrifuge at 12,000 rpm for 2 minutes and carefully discard the supernatant thoroughly without aspirating the precipitate. The residual dewaxing solution can be carefully removed with a small tip (10 µl).4. Add 180 µl of Buffer GTL and 20 µl of Proteinase K to the above tube and mix well with vortexing.5.

Note: If the columns are clogged, the sample size may be too large and consideration should be given to reducing the number of starting sections to 1-2.Optional step: If genomic DNA is to be removed, the following steps can be followeda. Add 350 µl of Buffer RW1 to the column, centrifuge at 12,000 rpm for 1 minute, discard the waste solution, and place the column back into the collection tube.b.

The whole extraction process does not take more than 10 minutes, without centrifugation to collect bacteria and resuspend the bacterium, directly add the unique super lysate Buffer L2 to the cultured bacterial solution, followed by neutralization, centrifugation and passing through the column, and the extracted plasmid can be as high as 30 µg, and maximize the removal of proteins, genomes and other impurities. The extracted plasmid DNA can be directly used for bacterial transformation, digestion, PCR, in vitro transcription, sequencing and other downstream experiments.Self-contained reagent: anhydrous ethanol.Pre-experiment Preparation and Important Notes1. The kit can be stored in a dry, room temperature (15-30°C) environment for 1 year. For longer storage, the centrifuge columns can be placed at 2-8°C.2. Before the first use, add all of the RNase A solution to Buffer N3, mix well, and store at 2-8°C.3. Anhydrous ethanol should be added to Buffer PW before the first use according to the instructions on the reagent bottle label.4. If there is any precipitation in Buffer L2 before use, please put it in a 37℃ water bath and keep mixing until the solution becomes clear before use.Operation steps1. Take 600 µl of bacterial culture into a 1.5 ml centrifuge tube (supplied).2. Add 100 µl of Buffer L2 to the above centrifuge tube and gently turn the solution up and down 8 times; the solution should change from turbid to a clear purple color, indicating complete lysis. The cleavage time should not exceed 2 minutes.3. Add 350 µl of Buffer N3 to the above centrifuge tube (please check that RNaseA has been added first) and immediately mix well by turning up and down about 8-10 times, at which point the solution should turn completely yellow and a yellow precipitate should form. centrifuge at 13,000 rpm for 2-3 minutes.4. Slowly pour the supernatant obtained in step 3 into the prepared adsorption columns (Spin Columns DM with Collection Tubes) to avoid sedimentation into the columns.5. Centrifuge at 13,000 rpm for 15 seconds, pour off the waste liquid in the collection tube, and put the adsorption column back into the collection tube.6. Add 150 µl Buffer PB to the adsorption column and centrifuge at 13,000 rpm for 15 seconds.7. Add 400 µl Buffer PW to the adsorption column (please check that anhydrous ethanol has been added first) and centrifuge at 13,000 rpm for 1 minute.8. Place the adsorbent column in a new centrifuge tube (self-provided), add 30-100 µl Buffer EB to the middle part of the adsorbent membrane, centrifuge at 13,000 rpm for 1 min, collect the plasmid DNA, and store at -20°C for long term storage.When the amount of extracted bacterial liquid is >600µl, the following procedure can be used:1. This kit can extract up to 3ml of bacterial solution, if the amount of extracted bacterial solution is more than 600µl, it is necessary to centrifuge the bacterial solution exceeding 600µl at 13,000rpm for 30 seconds (to collect the bacterial body), discard the supernatant and then add 600µl of bacterial solution, and then resuspend the bacterial body at the bottom of the tube thoroughly and then proceed to the following operation.2. Add 100µl Buffer L2 to the above centrifuge tube, gently invert the solution up and down 10 times, if the solution is not clarified, need to continue to invert the mixing until the solution becomes a clear purple color, the lysis time should not be more than 2 minutes. (If the solution is still turbid, the amount of bacteria is too large, and the amount of bacteria should be reduced appropriately.)3. Add 350 µl of Buffer N3 to the above centrifuge tube (please check that RNaseA has been added first) and immediately mix well by turning up and down until the purple solution turns completely yellow and a yellow precipitate is formed before proceeding to the next step. centrifuge at 13,000 rpm for 5 minutes.4. Transfer the supernatant to a new centrifuge tube, add 200 µl of isopropanol, mix up and down several times, mix well and transfer to the adsorbent column (Spin Columns DM with Collection Tubes), due to the amount of solution is too large, this time, it is necessary to centrifuge the column in two separate times, centrifugation at 13,000 rpm for 15 seconds, pour off the waste liquid in the collection tube, and put the adsorbent column back to the The adsorbent column should be placed back into the collection tube.5. Add 150 µl Buffer PB to the adsorption column and centrifuge at 13,000 rpm for 15 seconds.6. Add 400 µl Buffer PW to the adsorption column (please check that anhydrous ethanol has been added first) and centrifuge at 13,000 rpm for 1 minute.7.
