PolyMAC provides an effective and significantly improved method to achieve more complete enrichment of phosphopeptides. This highly selective enrichment method can be used for most complex samples because it offers optimal specificity and recovery rate. PolyMAC is a polymer-based immobilized metal ion affinity capture method with excellent phosphoproteome coverage and recovery rate. It is a soluble nanopolymer designed to interact with phosphopeptides in solution, and then be captured on a solid-phase carrier for washing and phosphopeptide elution. Compared with the commonly used titanium dioxide and immobilized metal ion affinity capture methods, PolyMAC has better reproducibility and enrichment of phosphorylated peptides, with the selectivity of phosphorylated peptides close to 95% and the recovery rate > 90%. Importantly, PolyMAC has very good recovery rate and selectivity for samples with low total protein phosphorylation levels.Experimental Flowchart of Phosphopeptide Protein (Peptide Fragment) Extraction Kit (P1456460)Product Components and Storage Conditions:P1456460Component24T48T96TStorageP1456460APolyMAC Beads0.75 mL1.5 mL3 mL4℃P1456460BPolyMAC Loading Buffer25 mL50 mL100 mLRTP1456460CPolyMAC Washing Buffer I25 mL50 mL100 mLRTP1456460DPolyMAC Washing Buffer II25 mL50 mL100 mLRTP1456460EPolyMAC Elution Buffer3.75 mL7.5 mL15 mLRTP1456460FPolyMAC Tips24T48T96TRTProduct Features:Easy to operate: Phosphopeptides can be prepared quickly, requiring only a metal bath and a conventional centrifuge.High stability: Strict quality inspection is conducted for each batch, ensuring high reproducibility of experimental results.Operating Procedure:1.Add 200 µL of Loading Buffer to the dried sample (50 µg - 100 µg) after enzymatic hydrolysis and desalting, and fully resuspend the sample.2.Vortex the PolyMAC Beads thoroughly (for 10 - 20 seconds), then take 25 µL into a 1.5 mL centrifuge tube, centrifuge instantaneously for 2 - 3 seconds, and then remove the upper storage solution. (The Beads settle quickly, so the operation should be fast when taking them.)3.Add the resuspended sample to the centrifuge tube containing PolyMAC Beads, then place it on a mixer, and shake vigorously at 26°C, >1200 rpm for 25 minutes.4.Add the sample to PolyMAC - Tips, first centrifuge at 20 g for 2 minutes, then centrifuge at 100 g for 1 minute to ensure that the sample solution flows out from the tip of the Tips into the centrifuge tube. (The rotation speed should not be too high, and the operation should be fast.)5.Wash once with 200 µL of Loading Buffer: first centrifuge at 20 g for 2 minutes, then centrifuge at 100 g for 1 minute, and discard the filtrate. Repeat this step 3 times. (The rotation speed should not be too high, and the operation should be fast.)6.Wash once with 200 µL of Washing Buffer I: first centrifuge at 20 g for 2 minutes, then centrifuge at 100 g for 1 minute, and discard the filtrate. Repeat this step 3 times. (The rotation speed should not be too high, and the operation should be fast.)7.Wash once with 200 µL of Washing Buffer II: first centrifuge at 20 g for 2 minutes, then centrifuge at 100 g for 1 minute, and discard the filtrate. Repeat this step 3 times. (The rotation speed should not be too high, and the operation should be fast.)8.Put the Tips into a new centrifuge tube to collect the eluted phosphopeptides.

The kit eliminates the need for phenol/chloroform extraction and is safe to handle. The extracted genomic DNA fragments are large, high purity, stable and reliable quality, suitable for PCR, fluorescence quantitative PCR, molecular labeling, library construction and other experiments.Self-contained reagent: anhydrous ethanolPre-experiment Preparation and Important Notes1. Repeated freezing and thawing of the sample should be avoided, as this may result in smaller fragments of extracted DNA and a decrease in the amount extracted.2. Anhydrous ethanol should be added to Buffer LP3 and Buffer GW2 according to the instructions on the label of the reagent bottle before first use. Check Buffer LP1 and Buffer LP2 for crystallization or precipitation before use. If crystallization or precipitation occurs, re-dissolve Buffer LP1 and Buffer LP2 in a 56°C water bath. Procedure1. Take about 100mg of fresh plant tissue or about 20mg of dry weight tissue and add liquid nitrogen to grind it fully.2. Collect the ground powder into a centrifuge tube (self-provided), add 400 µl Buffer LP1 and 6 µl RNase A (10 mg/ml), vortex and oscillate for 1 minute, and leave it at room temperature for 10 minutes to allow for full cleavage.Note: 1) Use vortex shaking or pipette blowing to fully lyses the tissue, incomplete tissue lysis will affect the final DNA yield. 2) Do not mix Buffer LP1 with RNase A prior to use.3. Add 130 µl Buffer LP2, mix well and vortex for 1 minute.4. Centrifuge at 12,000 rpm (~13,400 x g) for 5 minutes and transfer the supernatant to a new centrifuge tube (supplied).5. Add 1.5 times the volume of Buffer LP3 (check that anhydrous ethanol has been added before use) and mix thoroughly (e.g., 500 µl filtrate to 750 µl Buffer LP3).Note: Buffer LP3 should be mixed immediately after addition; precipitation may occur but will not affect subsequent experiments.6. Add all of the solution and precipitate obtained in the previous step to the adsorption columns (Spin Columns DM) that have been loaded into the collection tubes, 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 liquid in the collection tubes, and put the columns back into the collection tubes.7. Add 500 µl of Buffer GW2 to the adsorption column (check that anhydrous ethanol has been added before use), centrifuge at 12,000 rpm for 1 minute, pour off the waste liquid in the collection tube, and put the adsorption column back into the collection tube.Note: If the adsorbent membrane appears green, add 500 µl of anhydrous ethanol to the adsorbent column, centrifuge the column at 12,000 rpm for 1 minute, pour off the waste liquid in the collection tube, and put the adsorbent column back into the collection tube.8. Repeat step 7.9. 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 subsequent enzymatic reactions (digestion, PCR, etc.).10. Place the adsorption column in a new centrifuge tube (supplied), add 50-100 µl of Buffer GE or sterilized water dropwise to the middle of the adsorbent membrane, leave it at room temperature for 2-5 minutes, and centrifuge it at 12,000 rpm for 1 minute to collect the DNA solution. -The DNA solution was collected by centrifugation at 12,000 rpm for 1 min.Note: 1) If the downstream experiment is sensitive to pH or EDTA, you can use sterilized water for elution. The pH value of the eluent has a great influence on the elution efficiency, if you use water as the eluent, you should ensure that the pH value is 7.0-8.5 (you can use NaOH to adjust the pH value of the water to this range), and when the pH value is lower than 7.0, the elution efficiency is not high.2) Incubation at room temperature for 5 minutes prior to centrifugation increases yield.(3) If the final concentration of DNA is to be increased, the DNA eluate obtained in step 10 can be re-added to the adsorbent membrane and repeat step 10; if the elution volume is less than 100µl, the final concentration of DNA can be increased, but it may reduce the total DNA yield. If the amount of DNA obtained is less than 1µg, 50µl Buffer GE is recommended for elution.4) Because DNA stored in water is subject to acidic hydrolysis, for long-term storage, elution with Buffer GE and storage at -20°C are recommended...

Product IntroductionThe Quick Ligation Reaction Kit allows ligation of DNA sticky or flush ends in 5 minutes at room temperature (25°C). The kit contains Quick T4 DNA Ligase and 2×Quick Ligation Reaction Buffer optimized for fast and efficient DNA ligation.The ligation efficiency of Quick Ligation is equivalent to 1 hour of conventional ligation with T4 DNA Ligase. The Quick Ligation products can be used directly in routine bacterial transformation experiments.matters needing attention1. This kit enables most of the linkage reactions to reach the reaction endpoint within 5 minutes or less at 25°C. Increasing the reaction time will not enhance the reaction efficiency. If you use the rapid connection reaction after 1 hour, the conversion efficiency will be significantly reduced; if the rapid connection reaction at 25 ℃ overnight, the conversion efficiency will drop to 75%.2. 2×Quick Ligation Reaction Buffer contains ATP, which should be thawed on ice and mixed thoroughly before use. It is recommended to freeze the buffer in small tubes for the first time, so as to avoid repeated freezing and thawing, which will affect the efficiency of DNA ligation.3. Since T4 DNA Ligase contains glycerol, which is sticky and easy to hang on the wall, it is recommended to collect the liquid to the bottom of the tube by centrifugation for a short period of time before use, and the tip of the lance should not go too deep into the liquid surface when taking samples to avoid sticking to the tip of the lance and causing losses.4. If the quick ligation product is used for electrotransformation, the PEG in the quick ligation reaction system will affect the efficiency of electrotransformation, and it is recommended to use a centrifugal column to purify the ligation product from DNA before electrotransformation.Usage1. The reaction solution was prepared according to the following system:*The amount of Insert DNA used: the molar ratio of Vector DNA and Insert DNA is generally 1:3-1:8, and the appropriate molar ratio of Vector DNA and Insert DNA can be selected according to the experimental situation.Calculation of DNA molar number: DNA molar number (nmol)=DNA mass (ng)/( 660daltons x number of inserted DNA bases bp).2. mix gently and centrifuge briefly. react at 25°C for 5 minutes.Note: The reaction time should not exceed 15 minutes, otherwise the connection efficiency will be reduced.3. Do not perform heat inactivation reactions. Centrifuge instantly and collect the solution from the wall to the bottom of the tube.Note: Heat inactivation significantly reduces transformation efficiency due to the presence of PEG in the buffer.4. After the reaction, store the DNA ligation product at 0-4℃, and then carry out transformation experiments; you can also store the DNA ligation product at -20℃.Note: When transforming by chemical method, do not add more than 10% of the volume of the receptor cell for the ligation product.5. Heat shock the ligation product to transform 50 µl of receptor cells or take 1-2 µl of ligation product to electroshock transform 50 µl of receptor cells.Note: 1) When transforming by chemical method, do not add more than 10% of the volume of the receptor cell for the ligation product.(2) If the quick ligation product is used for electrotransformation, it is recommended to use a centrifugal column to purify the ligation product from DNA before electrotransformation because the PEG in the quick ligation reaction system will affect the efficiency of electrotransformation...
