VirCap® Oligo dT(25) Affinity Resin
For mRNA Purification
VirCap® Oligo dT(25) Affinity Resin is based on rigid, 50μm polymeric resin designed to isolate messenger RNA (mRNA). The resin backbone consists of crosslinked poly(styrene-divinylbenzene).
The polyhydroxy surface coating provides low non-specific binding. The surface is functionalized with poly(dT) and allows capture of mRNA through base pairing with the mRNA polyA tail.
VirCap® Oligo dT(25) Affinity Resin provides efficient capture and release under standard mRNA purification conditions. It thereby decreases process development time and enhances productivity. In addition, the selective nature of this resin allows a reduction in plasmid DNA and other transcription mix components. The resin is also stable at elevated temperatures for the breakdown of undesired higher-order structures if required.
- Easy mRNA purification from crude transcription mix to effectively remove plasmid DNA and other IVT components
- Simplified workflow helps to maximize efficiency, thereby reducing the complexity of subsequent polish steps
- Excellent scalability
- Non-animal derived
VirCap® Oligo ligands are manufactured using a synthetic manufacturing process that is free of animal components.
