All centrifugation steps are performed using a desktop centrifuge at room temperature. Operation steps:1. Material processing1a The cells cultured on the wall should be first processed into cell suspension (maximum extraction amount of 107 cells), collected cells, discarded the culture medium, and added 600 cells µ L Buffer RL (check if it has been added before use) β- Mercaptoethanol), repeatedly blow and beat to fully decompose.Attention: It is necessary to discard the culture medium completely, otherwise it will affect the lysis and subsequent nucleic acid purification steps.1b Take no more than 30 mg of animal tissue, grind it into fine powder with liquid nitrogen, and add 600 µ Buffer RL (check if it has been added before use) β- Mercaptoethanol, or directly add 600 µ L Buffer RL (check if it has been added before use) β- Mercaptoethanol, homogenization treatment.Attention: The homogenate should be sufficient, otherwise it will affect RNA production.2. Centrifuge the solution obtained in the previous step at 12000 rpm (~13400 × g) for 3-5 minutes. Carefully add the supernatant to the spin columns DM that have been loaded into the collection tube. Centrifuge at 12000 rpm for 30-60 seconds and collect the filtrate. Place the adsorption column DM in a new 2 ml collection tube at room temperature or 4 ℃ for DNA extraction. Attention: Ensure that there is no liquid residue on the adsorption column, and if necessary, repeat centrifugation until all liquids pass through the membrane of the adsorption column. Total RNA extraction3. Add 1 volume of 70% ethanol (prepared without RNase water) to the filtrate obtained in step 2, and mix well.4.

Repeat step 6.Centrifuge at 8.12000 rpm for 2 minutes and discard the waste liquid from the collection tube. Place the adsorption column at room temperature for a few minutes to thoroughly air dry. Attention: 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.).9.

Add 100 µ L Buffer PLS to obtain protein solution.Attention:1) The protein samples obtained by dissolving with Buffer PLS are suitable for SDS-PAGE and Western Blot detection, but not for Bradford method for protein quantification. If Bradford method is needed for protein quantification, 5% SDS can be used to dissolve the protein, or suitable protein dissolution buffer can be selected based on downstream experiments.2) The amount of dissolved protein buffer added is determined based on the initial sample size and specific downstream test requirements.3) The dissolved protein can be stored at -20 ℃ for several months and at 2-8 ℃ for several days.If protein samples require SDS-PAGE electrophoresis, the following operations can be performed:19. Add protein loading buffer to the protein sample, denature at 95 ℃ for 5-10 minutes, and cool the sample to room temperature. Centrifuge at 20.12000 rpm for 1 minute, extract the supernatant for downstream SDS-PAGE or Western blot tests...

The product can handle liquid samples of 0.1-1 ml, and the elution volume of the configured high-efficiency micro adsorption column can be as low as 20 µl. The purified DNA is of high yield and quality, with maximum removal of proteins, pigments, lipids, and other inhibitors, and the rate of free DNA yield is highly dependent on the type of samples, storage conditions, time, and inter-individual variations. The quality of free DNA obtained from purification is stable and reliable, and can be directly used in molecular biology experiments such as PCR, fluorescence quantitative PCR and second generation sequencing.Self-contained reagents: anhydrous ethanol, isopropanol.Pre-experiment Preparation and Important NotesAdd 5 ml of Proteinase K Storage Buffer to Proteinase K to dissolve it and store it at -20℃. Do not leave the prepared Proteinase K at room temperature for a long time.Repeated freezing and thawing of the sample should be avoided, as this can lead to a decrease in extraction.This kit can extract 0.1-1 ml of liquid samples.Before use, please check Buffer CL, Buffer CB for crystallization or precipitation, if there is any crystallization or precipitation, please re-dissolve Buffer CL, Buffer CB by incubation at 56℃ in a water bath.Before first use isopropyl alcohol should be added to Buffer CB according to the instructions on the reagent bottle label, mixed well, and labeled on the reagent bottle label.Before the first use, anhydrous ethanol should be added to Buffer GW1 and Buffer GW2 according to the instructions on the label of the reagent bottle, mixed well, and labeled on the label of the reagent bottle.Preheat the water bath to 60°C before starting the experiment.The elution buffer Buffer EBL can be preheated to 60°C and used.Operation stepsAdd 20 µl of Proteinase K to the centrifuge tube (supplied).Add 200 µl of serum/plasma sample.Note: When the sample volume exceeds 200 µl, please increase the amount of Proteinase K, Buffer CL and Buffer CB reagents in equal proportions, and the specific amount of reagents added can be referred to the attached table.3. Add 160 µl Buffer CL, mix upside down and shake vigorously for at least 30 seconds.4. Incubate at 60°C for 30 minutes, during which time mixing was inverted several times.Note: Incubation of 200µl serum/plasma samples at 60°C for 10-15 minutes is sufficient.Add 360 µl of Buffer CB (check for addition of isopropanol before use) and shake until thoroughly mixed.Ice bath for 5 minutes and centrifuge briefly to concentrate the liquid on the walls and wall caps to the bottom of the tube.Add all of the solution obtained in step 6 to the adsorption columns (Spin Columns DF) that have been loaded into the collection tubes, and 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 solution from the collection tubes, and put the columns back into the collection tubes.Add 500µl of Buffer GW1 to the adsorbent column (check that anhydrous ethanol is added before use),centrifuge the column at 12,000rpm for 30 seconds, pour off the waste liquid in the collection tube, and put the adsorbent column back into the collection tube.Add 750 µl Buffer GW2 to the adsorbent column (check that anhydrous ethanol is added before use), centrifuge at 12,000 rpm for 30 seconds, pour off the waste liquid in the collection tube, and put the adsorbent column back into the collection tube.10. Add 750 µl of anhydrous ethanol to the adsorbent column and centrifuge at 12,000 rpm for 30 s. Pour off the waste liquid in the collection tube and put the adsorbent column back into the collection tube.11. 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 the subsequent enzymatic reaction.12. Place the adsorption column in a new centrifuge tube, add 20-100 µl Buffer EBL or sterilized water to the middle part 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, you can use sterilized water for elution. 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 (you can use NaOH to adjust the pH value of water to this range), and the elution efficiency is not high when the pH value is lower than 7.0.2) Preheat the elution buffer BufferEBL to 60℃ and use it, and incubate it at room temperature for 5 minutes before centrifugation to increase the yield.3) If the final concentration of DNA is to be increased, the resulting solution can be reintroduced into the adsorption column and left at room temperature for 2-5 minutes and centrifuged at 12,000 rpm for 1 minute.4) Because DNA preserved in water will be affected by acidic hydrolysis, for long-term storage, it is recommended to elute it with Buffer EBL and store it at -20℃.Table: Recommended reagent additions for different sample sizes...
