The Kit contains AnteoBind™activated 200 nm magnetic particles that give you increased antibody binding capacity and functionality, while the included blocking buffer decreases background noise.Reduce reagent preparation time; remove traditional surface preparation steps such as EDC and replace these steps with the 200 nm pre-activated magnetic particles provided. This Kit reduces aggregation and gives you the freedom and ability to produce multifunctional particles for diverse applications, including dual labelling.For lateral flow tests, magnetic particles are easier to handle than gold. Magnetic separation removes the need to perform centrifugation and filtration concentration. Magnetic particles can provide greater sensitivity than gold during lateral flow tests.Binding Capacity and Polydisperity IndexBinding Capacity: > 50 µg IgG/mgPolydispersity Index (PdI)*: < 0.3* The Polydispersity Index (PdI) is dimensionless and determined using Dynamic Light Scattering (DLS). The PdI is scaled such that values smaller than 0.05 are rarely seen and values greater than 0.7 indicate that the sample has a very broad size distribution and poor monodispersity.Particle based Immunoassays, Lateral Flow, Bioseparations and Immunoprecipitation...

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...
