Due to the high sensitivity of eukaryotic cells to endotoxins, the presence of endotoxins in plasmids can greatly reduce the transfection efficiency of eukaryotic cells. This reagent kit provides a simple, fast, and efficient new method for extracting endotoxin free plasmids. The extracted plasmids remove endotoxins to the maximum extent possible and can effectively remove contamination of genomic DNA, RNA, proteins, etc. The operation is simple and convenient. This reagent kit is suitable for extracting 1-5mL of bacterial solution. On the basis of alkaline lysis of cells, it efficiently and specifically binds plasmid DNA through a new silicon-based membrane. Each adsorption column can adsorb up to 40% µ The plasmid DNA of g is effectively removed using a special buffer system and endotoxin removal filter column, effectively removing impurities such as endotoxins and proteins. The plasmid obtained from this kit has high purity and stable quality, making it particularly suitable for cell transfection. It can also be used for downstream experiments such as DNA sequencing, PCR, PCR based mutations, in vitro transcription, transformed bacteria, and endonuclease digestion.Self prepared reagents: anhydrous ethanol, isopropanol.Preparation and important precautions before the experiment：1. All components can be stably stored for 1 year in a dry, room temperature (15-30 ℃) environment. The adsorption column can be stored for a longer time at 2-8 ℃. Buffer P1 with RNase A added can be stably stored for 6 months at 2-8 ℃. 2. Before the first use, add all RNase A solution to Buffer P1, mix well, and store at 2-8 ℃. Before use, let it sit at room temperature for a period of time. After returning to room temperature, use.3.Before the first use, anhydrous ethanol should be added to the Buffer PW according to the instructions on the reagent bottle label.4. Before use, please check if there is any crystallization or precipitation in Buffer P2 and Buffer E3. If there is any crystallization or precipitation, you can take a water bath at 37 ℃ for a few minutes to restore clarity.5. Be careful not to come into direct contact with Buffer P2 and Buffer E3, and immediately cover them tightly after use.6.The amount and purity of plasmid extraction are related to factors such as bacterial culture concentration, strain type, plasmid size, and plasmid copy number.Operation steps：1. Take 1-5 mL of overnight cultured bacterial solution and add it to a centrifuge tube (provided). Centrifuge at 13000 rpm (~16200 × g) for 30 seconds to collect bacteria, and try to discard all the supernatant as much as possible.2. Add 250 to the centrifuge tube containing bacterial sediment µ L Buffer P1 (please check if RNase A has been added first), mix thoroughly with a pipette or vortex oscillator, and suspend bacterial precipitation.Attention: If the bacterial blocks are not thoroughly mixed, it will affect the cracking effect, resulting in low extraction amount and purity.3. Add 250 to the centrifuge tube µ L Buffer P2, gently invert and mix 8-10 times, allowing the bacterial cells to fully lyse. Leave at room temperature for 3-5 minutes. At this point, the solution should become clear and viscous.Attention: Mix gently and do not shake vigorously to avoid interrupting genomic DNA and mixing genomic DNA fragments in the extracted plasmid. If the solution does not become clear, it indicates that the bacterial count may be too high and the lysis may not be complete. The bacterial count should be reduced.4. Add 250 to the centrifuge tube µ L Buffer E3, immediately invert and mix 8-10 times until white flocculent precipitates appear. Let it stand at room temperature for 5 minutes. Centrifuge at 13000 rpm for 5 minutes, extract the supernatant, and add it to a filter column (Endo Remove FM). Centrifuge at 13000 rpm for 1 minute to filter, and collect the filtrate in a centrifuge tube (self provided).Attention: After adding Buffer E3, it should be mixed evenly immediately to avoid local precipitation. 5. Add 225 to the filtrate µ Mix L isopropanol upside down.6. Column balance: Add 200 to the spin columns DM that have been loaded into the collection tube µ L Buffer PS, centrifuge at 13000 rpm for 1 minute, discard the waste liquid in the collection tube, and place the adsorption column back into the collection tube.7. Transfer the mixed solution of filtrate and isopropanol from step 5 to an equilibrium adsorption column (already loaded into a collection tube).8.13000 rpm for 1 minute, discard the waste liquid in the collection tube, and place the adsorption column back into the collection tube.Attention: The maximum volume of the adsorption column is 750 µ L. If the sample volume is greater than 750 µ L can be added in batches. 9. Add 750 to the adsorption column µ L Buffer PW (please check if anhydrous ethanol has been added first), centrifuge at 13000 rpm for 1 minute, and discard the waste liquid in the collection tube.10. Place the adsorption column back into the recovery manifold and centrifuge at 13000 rpm for 1 minute. Note: 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.).11. Place the adsorption column in a new collection tube and add 50-100 to the middle of the adsorption membrane µ L Endo Free Buffer EB, let it stand at room temperature for 2-5 minutes, centrifuge at 13000 rpm for 2 minutes, and collect the plasmid solution into a centrifuge tube- Store the plasmid at 20 ℃.Note: 1) To increase the efficiency of plasmid recovery, the obtained solution can be added back to the adsorption column, left at room temperature for 2-5 minutes, centrifuged at 13000 rpm for 2 minutes, and collected into a centrifuge tube.2) When the plasmid copy number is low or>10 kb, preheating the Endo Free Buffer EB in a water bath at 65-70 ℃ can increase the extraction efficiency...

The protein on the glue is transferred toAfter coating the carrier membrane, incubate it with the blocking solution in the reagent kit for 5 minutes, and then incubate the carrier with the primary antibody treated with antibody reaction solutionAfter washing the membrane three times (5 minutes each time), it can undergo luminescence or color detection. This reagent kit is designed for target protein oneThe use of an experimental system derived from rabbits.Notes:1. Customers need to prepare their own rabbit source primary antibody.2. Before using Blocking Buffer blocking solution, Antibody Pretreat Solution (HRP/Rabbit) antibody reaction solution (rabbit), and Wash Buffer (10 x) rinse solution, please mix thoroughly.3. If there is precipitation in the rinsing solution when stored at 2-8 ℃, please restore it to room temperature, dissolve the precipitation, and use it normally. The 1x rinsing solution can be stored at room temperature for one month.4. It is recommended to stain the membrane with reagents such as spring red after the transfer is completed, and cut off any excess parts on the membrane to increase the efficiency of the reagents.5. The optimal dilution amount for primary antibody and antibody reaction solution HRP (rabbit) needs to be determined through preliminary experiments.6. Antibody reaction solution HRP (rabbit), antibody dilution solution, and antibody dosage can be increased or decreased proportionally according to the size of the membrane.7. The antibody dilution solution containing the first antibody can be recycled and reused once. Antibodies with low specificity and affinity are not recommended for repeated use. If the recovered antibody is used within 1-2 days and stored at 2-8 ℃ for long-term storage, please freeze it at -20 ℃ to avoid repeated freeze-thaw cycles.8. If there is a high background, please adjust the amount of antibodies and increase the number of times the film is washed.9. All reagents in the reagent kit should be stored at 2-8 ℃ to avoid freezing and thawing.Operation steps:This product is suitable for the sealing and antibody incubation steps after membrane transfer, taking a 5 cm x 8 cm membrane as an example:1. Preparation of rinsing solution: Dilute 10 ml of Wash Buffer (10 x) with distilled water to 100 ml, which is 1 x Wash Buffer. Set aside. Use 8-10 ml for each film wash.2. Sealing: After the membrane transfer is completed, immerse the membrane in 10 ml Blocking Buffer and seal at room temperature for 5 minutes.3. Rinse: Pour off the sealing solution, add 8-10 ml of 1 x Wash Buffer, and rinse at a high speed on a shaker for 1 minute.4. Prepare antibody incubation solution while washing the membrane: Take Antibody Pretreat Solution (HRP/Rabbit) 100 µ Add rabbit derived primary antibody 3-10 into the centrifuge tube µ g. Suck and beat the gun head until thoroughly mixed, and incubate at room temperature for 5 minutes. Add to 10 ml Dilution Buffer and mix well. Note: 1) The dosage of primary antibody can also be adjusted according to the dilution of the antibody. Taking the final dilution of antibodies at 1:1000 as an example, take 100 µ Add HRP (rabbit) antibody reaction solution into the EP tube and add 10 µ Add the first antibody to 10 ml of antibody diluent, mix well, and incubate at room temperature for 5 minutes. 2) If the membrane area is small, the amount of antibodies, reaction solution, and diluent can be reduced proportionally.5. After completing step 3, pour out the rinsing solution and add the antibody incubation solution mixed with primary antibody, Antibody Pretreat Solution (HRP/Rabbit), and Dilution Buffer to the membrane (ensuring that the incubation solution completely submerges the membrane surface). Incubate at room temperature on a shaker at a speed of about 60 rpm for 40 minutes.6. Discard (recover) the antibody incubation solution and rinse 3-5 times with the prepared 1 x Wash Buffer, each time for 3 minutes.7. Conduct subsequent testing.
