Based on the lysis of cells by alkaline lysis method, it adopts a unique silica matrix membrane adsorption technology and reagent formulation, and efficiently and exclusively binds plasmid DNA in solution by centrifugal adsorption columns in a high-salt state, and each adsorption column can adsorb a maximum of 30 µg of plasmid DNA, and removes proteins, genomes, RNAs, and other impurities to the greatest extent possible. The plasmid DNA obtained can be directly used for cell transfection, PCR, digestion, sequencing, ligation and other biological experiments.Self-contained reagent: anhydrous ethanol.Pre-experiment Preparation and Important Notes1. All components can be stably stored in dry, room temperature (15-30℃) environment for 1 year, the adsorption column can be stored at 2-8℃ for a longer period of time, and Buffer P1 with RNase A can be stably stored at 2-8℃ for 6 months.2. Before the first use, add all the RNase A solution into Buffer P1, mix well, and store it at 2-8°C. Before use, leave it at room temperature for a period of time, and then use it after recovering to room temperature.3. Anhydrous ethanol should be added to Buffer PW according to the instructions on the label of the reagent bottle before first use.4. If precipitation is found in Buffer P2, Buffer N3, or Buffer PB before use, the clarification can be restored by water bath at 37℃ for a few minutes (please do not shake Buffer P2 violently).5. Be careful not to touch Buffer P2, Buffer N3 and Buffer PB directly, and tighten the lid immediately after use.6. The amount and purity of extracted plasmid is related to the concentration of bacterial culture, strain type, plasmid size, plasmid copy number and other factors.Procedure1. Take 1-5 ml of the overnight culture and add it to a centrifuge tube (self-prepared), centrifuge for 30 seconds at 13,000 rpm (~16,200×g) to collect the bacterial precipitate, and discard the supernatant as much as possible.2. Add 250 µl of Buffer P1 to the centrifuge tube with the bacterial precipitate (please check that RNase A has been added first), mix well using a pipette or vortex shaker, and suspend the bacterial precipitate.Note: If the bacterial mass is not thoroughly mixed, it will affect the lysis effect, resulting in low extraction and purity.3. Add 250µl of Buffer P2 to the centrifuge tube and mix gently up and down 4-6 times, mixing well to lyse the organisms, at which point the solution should become clear and viscous.Note: Mix gently, do not shake vigorously to avoid interrupting the genomic DNA and causing the extracted plasmid to be mixed with genomic DNA fragments. This step should take no more than 5 minutes to avoid damage to the plasmid.4. Add 350 µl of Buffer N3 to the centrifuge tube and immediately mix gently up and down for 8-10 times, mixing well so that a white flocculent precipitate should appear. centrifuge at 13,000 rpm for 5 minutes.Note: Buffer N3 should be mixed immediately after addition to avoid localized precipitation.5. Transfer the supernatant obtained in step 4 to the Spin Columns DM that have been loaded into the collection tube, centrifuge at 13,000 rpm for 30 seconds, pour off the waste liquid from the collection tube, and place the column back into the collection tube.6. Add 150 µl Buffer PB to the adsorption column and centrifuge at 13,000 rpm for 30 seconds.7. Add 400 µl Buffer PW to the adsorption column (please check that anhydrous ethanol has been added first), centrifuge at 13,000 rpm for 1 minute, and pour off the waste liquid in the collection tube.8. Place the adsorbent column in a new centrifuge tube (supplied), add 50-100 µl Buffer EB to the middle of the adsorbent membrane, leave it at room temperature for 2 minutes, centrifuge at 13,000 rpm for 1 minute, and collect the plasmid solution into the centrifuge tube. -The plasmid solution was collected into the centrifuge tube.Note: 1) To increase the recovery efficiency of the plasmid, the resulting solution can be reintroduced into the adsorbent column, left at room temperature for 2 minutes, centrifuged at 13,000 rpm for 1 minute, and the plasmid solution collected into a centrifuge tube.2) For low plasmid copy number or >10 kb, Buffer EB is preheated at 65-70°C in a water bath to increase extraction efficiency...

The unique separation column is used for homogenization and filtration of high viscosity plant or fungal lysates, while the silicon matrix membrane is used to adsorb the RNA for purification, so that various contaminants, such as polysaccharides, are effectively removed by washing, and the eluted RNA can be directly used in various downstream experiments. The molecular weight of RNA extracted by this kit is more than 200 bases, with high purity and almost no DNA residue. For RNA experiments that are very sensitive to trace DNA, the residual DNA can be removed by digestion on a column using RNase-free DNase. The extracted RNA can be used in Northern Blot, Dot Blot, RT-PCR and in vitro translation experiments.Self-contained reagents: β-mercaptoethanol, anhydrous ethanol (freshly opened or for RNA extraction).Pre-experiment Preparation and Important Notes1. To prevent RNase contamination, attention should be paid to the following aspects:1) Use RNase-free plastics and tips to avoid cross-contamination.2) RNase-free water should be used to prepare the solution.(3) Operators wear disposable masks and gloves, and change gloves diligently during the experiment.2. To prevent RNase contamination, attention should be paid to the following aspects:1) Use RNase-free plastics and tips to avoid cross-contamination.(2) Glassware should be dry-roasted at 180°C for 4 hours before use, and plasticware can be soaked in 0.5M 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.3. Avoid repeated freezing and thawing of the extracted samples, otherwise it will affect the amount and quality of RNA extraction.4. Please add β-mercaptoethanol to Buffer RL before use, add 10µl of β-mercaptoethanol to 1ml of Buffer RL, it can be stored for 1 month at room temperature. Buffer RL with β-mercaptoethanol can be stored at room temperature for 1 month. β-mercaptoethanol is not required for use of Buffer RLC.5. Anhydrous ethanol should be added to Buffer RW2 before first use according to the instructions on the reagent bottle label.6. If precipitation occurs in Buffer RL and Buffer RLC, heat to dissolve and leave at room temperature.7. All centrifugation steps are carried out at room temperature and all steps are performed quickly. Procedure1. 50-100 mg of plant tissue is quickly ground to a powder in liquid nitrogen and added to 600 µl of Buffer RL (check for addition of β-mercaptoethanol before use) or Buffer RLC. vortexing and oscillating to allow for adequate lysis.Note: 1) The main component of Buffer RL is guanidine isothiocyanate, which is suitable for lysis of most plant tissues. However, in some plant tissues (e.g. endosperm of corn), due to the special secondary metabolites, guanidine isothiocyanate causes precipitation of the sample, resulting in poor RNA extraction, in this case, Buffer RLC can be added instead of Buffer RL.2) Incubation at 56°C for 1-3 minutes helps tissue lysis, but do not incubate at high temperatures for plants with high starch content.2. Transfer all the liquid obtained in step 1 to an adsorption column (Spin Columns FL) that has been loaded into a collection tube, centrifuge at 12,000 rpm (~13,400 x g) for 2 minutes, and transfer the supernatant from the collection tube to a new centrifuge tube (supplied).Note: 1) The tip of the tip of the gun can be cut off when aspirating liquids to facilitate sampling.2) Spin Columns FL removes most of the debris, but a small portion will still flow out and a precipitate will form in the collection tube after centrifugation, so be careful to avoid aspirating the precipitate when proceeding to the next step.3. Add 0.5 times the volume of anhydrous ethanol to the clean lysate obtained in step 2 and mix rapidly.Note: Precipitation may occur upon addition of ethanol, but does not affect subsequent tests.4. Transfer the solution obtained in the previous step to the Spin Columns RM in the collection tube. If it is not possible to add all of the solution to the column at one time, centrifuge the column at 12,000 rpm for 15 seconds in two batches, discard the waste solution and put the column back into the collection tube.5. Add 350 µl Buffer RW1 to the adsorbent column, centrifuge at 12,000 rpm for 1 min, discard the waste liquid and put the adsorbent column back into the collection tube.6. Preparation of DNase I mixture: Take 52µl of RNase-Free Water, add 8µl of 10×Reaction Buffer and 20µl of DNase I (1U/µl) to it, mix well, and make a final volume of 80µl of reaction solution.7. Add 80µl of DNase I mixture directly to the adsorption column and incubate at 20-30°C for 15 minutes.8. Add 350 µl of Buffer RW1 to the adsorption column, centrifuge at 12,000 rpm for 1 minute, discard the waste liquid and put the column back into the collection tube.9. Add 500 µl of Buffer RW2 to the column (check that anhydrous ethanol is added before use), centrifuge at 12,000 rpm for 15 seconds, and discard the waste solution.10. Repeat step 9.11. Place the adsorbent column back into the collection tube, centrifuge at 12,000 rpm for 1 minute, and allow the column to come to room temperature for a few minutes to thoroughly dry out the anhydrous ethanol in the adsorbent column.Note: The purpose of this step is to remove residual ethanol from the adsorption column; ethanol residue can interfere with subsequent enzymatic reactions (zymography, PCR, etc.).12. Load the adsorption column into a new centrifuge tube, add 30-50 µl of RNase-Free Water to the middle of the adsorbent membrane, leave it at room temperature for 1 minute, centrifuge at 12,000 rpm for 1 minute, and store the resulting RNA solution at -70°C to prevent degradation.Note: 1) The volume of RNase-Free Water should not be less than 30 µl, too small volume affects the recovery rate.2) If you want to increase the RNA yield, repeat step 12 with 30-50 µl of fresh RNase-Free Water.3) If the RNA concentration is to be increased, the resulting solution can be reintroduced into the adsorption column and step 12 repeated...
