Both supports are designed to resolve full length from n–1, n+1, and other failure sequences not possible with other columns. Retention times and selectivity can be controlled by choice of salt, pH, and solvent. Therefore, the separation can be tailored to the requirements of many different oligonucleotide analysis challenges. Achieve n, n-1 resolution for oligonucleotides.Resolve oligonuleotide linkage and stereoisomers.Assay phosphorothioate purity.Attain selectivity control with eluent pH, salt, and solvent.Resolve RNA with aberrant (2’–5’) links from normal SSRNA.The DNAPac PA200 is packed with a pellicular anion-exchange resin composed of an 8 μm diameter nonporous polymeric substrate to which quaternary amine-functionalized Thermo Scientific™ Dionex™ MicroBeads™ are bound. The rapid mass transport characteristics of this resin result in high-resolution oligonucleotide separations. The DNAPac PA200 RS is smaller, with 4 μm diameter resin for bio-UHPLC separations. These rapid separation (RS) columns are designed for use with the Thermo Scientific™ Dionex™ UltiMate™ 3000 BioRS system, with an operational backpressure limit of 10,000 psi. Columns packed with smaller particles improve resolution and offer better performance.The DNAPac PA200 and PA 200 RS can be operated under denaturing conditions, such as high temperature (up to 85 °C), high-pH eluents (up to pH 12.5), or by the inclusion of chaotropic agents (such as Urea).These columns offer the highest-quality phase stability over a broad pH range, deliver exceptional resolution, and support high-throughput separations. DNAPac PA200 and PA 200 RS columns support resolution of normal-length oligonucleotides (8- to 30- mer), extended-length oligonucleotides (30- to 70-mer), linear double-stranded DNA, and supercoiled versus nicked/linear DNA.Analytical separations on the DNAPac PA200, 8μm, 4 mm diameter column can be scaled directly to larger diameter columns so preparative methods can be conveniently developed using small samples. Scaling the flow rate and sample size up for the 9 × 250 mm and 22 × 250 mm column yields essentially identical chromatography.Column SpecificationsDNAPac PA 200DNAPac PA 200 RSColumn Chemistry55% crosslinked nonporous polymer with Quaternary amine functionalized latex MicroBeadsParticle Size8 μm4 μmIon Exchange Capacity~ 14 μeq/mL~ 20 μeq/mLpH Range4 to 10 (12.5 with salt, see manual)Pressure Maximum4,000 psi10,000 psiTemperature rangeRecommended operating temperature: Controlled ambient Temperature limit: 85 °CFlow RatesRecommend 0.1 to 1.5 mL/minOrganic Solvent Limit100% acetonitrile or methanol for cleaningTypical EluentsHigh purity water (18 megohm-cm), sodium chloride, sodium perchlorate, buffers, sodium acetate and sodium hydroxide.Detergent CompatibilityCompatible with nonioinic, cationic or zwitterionic detergents.Resolution of oligonucleotides using DNAPac PA200 column (8μm).

PA100 is a high-resolution anion-exchange column that provides single-base resolution. It is stable under denaturing conditions, rugged, reliable, and can be readily scaled up. The DNAPac PA100 is a 13 μm pellicular, nonporous polymeric resin with bound quaternary amine-functionalized MicroBeads?. The rapid mass-transport characteristics of this resin result in very high-resolution oligonucleotide separations.Capable of n, n-1 resolution for oligonucleotidesResolves oligonucleotides with secondary structuresCompatible with solvent, high pH, and high temperaturesAnalyzes phosphorothioate-based clinical samplesProvides easy scale-upThe MicroBead resin used in DNAPac columns provides high-resolution separations to ensure maximum peak purity, and makes linear scale-up of your separation easy. For more complex separations, the polymeric properties of the DNAPac PA100 allows great flexibility to select ideal conditions, including high pH, high temperature, or chaotropic agents.Synthetic oligonucleotides can be screened for production yield and failure sequences using the DNAPac PA100. Unit-base resolution of synthetic oligonucleotides to 60 bases and beyond has been demonstrated. The DNAPac PA100 can even be operated under denaturing conditions. Either high temperature (up to 90 °C) or high-pH eluents (up to pH 12.5) can be used to eliminate hydrogen bonding, allowing resolution of problem sequences such as self-complementary sequences or poly-G stretches.Separates RNA / Double-Stranded DNAThe DNAPac PA100 is ideally suited for the purification and analysis of synthetic RNA. Failure sequences are easily separated from the full-length product. Double-stranded DNA, such as plasmids, or restriction fragments are also separated.Analytical separations on the 4 mm diameter column can be scaled directly to larger diameter columns so preparative methods can be conveniently developed using small samples. The loading capacity of the DNAPac PA100 (4 × 250 mm) column is from 1 to 100 μg. Scaling the flow rate and sample size up for the 9 × 250 mm and 22 × 250 mm column yields essentially identical chromatography.DNAPac?

The exceptionally high resolution provides superior purity and yields compared to other ion-exchange or reversed-phase columns available. The DNASwift column is ideal for therapeutic and diagnostic research, which have very high purity and yield oligonucleotides purification requirements.Highest resolution for oligonucleotide purification available, providing high purity and yields.Exceptionally high capacity provides exceptionally high yields with high purity.Refined selectivity, as with the DNAPac® column, for high resolutionCompatible with high pH, solvents, and high temperatures.The DNASwift monolith column is specifically designed to provide exceptionally high resolution, laboratory-scale purification of oligonucleotides by anion-exchange chromatography. The use of oligonucleotides in therapeutic and diagnostic research is rapidly expanding. Oligonucleotides for these areas of research must be of the highest purity. DNASwift monolith columns provide high resolution and capacity, resulting in superior purity and yield compared to other ion-exchange and revered-phase columns available.The DNASwift column is a unique porous polymer monolith specifically designed for superior performance in oligonucleotide purification. The column is a pressure and chemically stable monolith support coated with functionalized latex nanobeads. These latex nanobeads, beads with strong anion-exchange functional groups, optimized for oligonucleotide separations, are similar to those of the industry leading DNAPac columns. Similarly, the nanobeads contribute to the DNASwift column' s exceptionally high resolution and selectivity control. The monolith, a polymer cylinder with interconnected flow through channels, provides fast mass transfer which contributes to the exceptionally high resolution of the DNASwift column. The porous monolith also offers low back pressure, allowing increased flow rates with minimal loss of resolution. The combination of functionalized latex nanobeads and monolith technology results in the DNASwift column having very high capacity, exceptionally high resolution, and refined selectivity control, which results in superior purity and yield of full length oligonucleotide products purified from crude oligonucleotide samples. This makes the DNASwift column ideal for oligonucleotide, therapeutic, and diagnostic research. Additionally, it provides DNASwift columns with the capability to successfully purify difficult oligonucleotide products.DNASwift SAX-1S SpecificationsSurface chemistryQuaternary amineColumn dimension5 × 150 mmBase matrixPolymethacrylateOligonucleotide binding capacity~20 mg/mL 20-merTotal binding capacity per column~50 mg 20-merBed height130 mmBed volume2.5 mLpH Range6–12.4 for operation 2–14 for cleaning NOTE: [Salt]≥Equimolar to [NaOH] requiredRecommended Ffow rate0.5–2.5 mL/min Maximum flow rate3 mL/minOperating column pressure≤ 1500 psi 10.3 MPaMaximum operating temperature85 °CSolvent compatibilityMost common organic solvents (e.g., CH3CN, CH3OH)Product Data SheetsDNASwift Monolith Column for Oligonucleotide Purification Data SheetGuidesDNASwift Monolithic Column for Oligonucleotide Purification Product Manual
