Improve mRNA product purity

Superior mRNA therapeutics with precise dsRNA removal

Efficient removal of dsRNA is essential to ensure the safety and efficacy of mRNA biotherapeutics. AVIPure dsRNA Clear affinity resin prepacked in OPUS columns has emerged as a highly effective solution for this challenge, offering precise and reliable separation of dsRNA from single-stranded RNA (ssRNA). By leveraging specific binding interactions, affinity chromatography enhances the purity and quality of RNA-based therapeutics, ultimately contributing to their success in clinical applications.

AVIPure dsRNA Clear is the first and only bead based, affinity chromatography solution for removing dsRNA impurities from mRNA preparations. The solution is targeted, eliminates the use of organic solvents (EtOH), negates the need for a non-specific and non-scalable removal methods and sets the standard for dsRNA impurity clearance in mRNA production processes.

Product performance

Optimized dsRNA clearance for therapeutic success

To help scientists to accelerate therapeutic development, AVIPure dsRNA Clear OPUS columns are designed to remove double stranded RNA from complex feedstocks via affinity chromatography. The resin enables users to maintain high target molecule recovery while eliminating dsRNA from the feedstock. Easily scale from process development to clinical and commercial manufacturing using this resin, which is available exclusively in OPUS pre-packed chromatography columns.

The highest clearance of dsRNA, typically two to three log reduction, is observed with optimized IVT feeds with already low dsRNA levels where RNA presents as a single, sharp band on a gel. Even in unoptimized feeds with higher dsRNA content, or where RNA appears as a smear or ladder on a gel, users are able to achieve a few fold reduction of dsRNA.

Performance and Efficiency

  • High Dynamic Binding Capacity: ≥0.4 mg dsRNA/mLcolumn volume at 10% breakthrough
  • Selectivity: Resin selectively binds double stranded RNA in high salt (>0.5 M NaCl) from pH 7.2-9.5 for easily impurity removal. mRNA, circular RNA, and self-amplifying RNA flows through.
  • Purity and Yield: Superior product purity and yield, delivering excellent target molecule recovery with limited product loss

Operational Benefits

  • Ease of Use: Resin operates in flow through mode with aqueous buffers. No elution required.
  • Reduced Processing Time: High volumetric throughput with optimal clearance achieved with 1-minute residence time.
  • No solvents required: Only aqueous buffers are required, no solvents or heating are needed to operate this resin.

Regulatory Compliance and Safety

  • Compliance with Industry Standards: Large scale columns are ready for use in GMP processing.
  • Biocompatibility and Safety: AVIPure dsRNA Clear OPUS columns are free from animal derived components. Residual ligand ELISA kit available for detection of leached ligand.

Support and Service

  • Technical Support: Expert technical support is available for product implementation and process optimization.
