AccuPlex Recombinant Virus Materials

The Safest, True Full-Process Control

The key to successful development, validation, and implementation of molecular diagnostic assays is the availability of abundant, non-infectious, and consistently-manufactured reference materials.

AccuPlex provides the power of flexibility to create custom solutions to your most challenging reference material needs.

Compatible with multiplexed RT-PCR and NGS-based assays, AccuPlex custom recombinant virus materials are constructed with a replication-defective mammalian virus, producing a safe, non-infectious material (Figure 1). With a protein coat and lipid bilayer, these mammalian virus-based reference materials resemble the complexity of virus targets found in clinical samples.

Figure 1:

1. RNA sequence from the pathogenic virus of interest is chosen
2. DNA synthesis and cloning is performed to produce the recombinant RNA
3. Recombinant RNA and helper RNA are co-transfected into the mammalian cells, allowing the encapsulation of recombined RNA
4. Exocytosis of the mature enveloped RNA virus with the RNA sequence of the virus of interest occurs

AccuPlex Solves Development Challenges

• Non-infectious and replication-defective for safe and effective handling of positive material
• Fully-extractable with a real viral protein coat to serve as a full-process control
• Accepts multiple sequences from same or different RNA viruses, customizable to your sequences of interest
• Digital PCR (ddPCR) QC step allows for a wide range of titer levels, offers flexible concentrations
• Compatible with multiple sample matrices including DBS, buffer, serum, and semen
• Stability studies confirm product is stable at 4°C, room temperature, and elevated temperatures

Patient-Like Material Evaluates Entire Workflow

Unlike other technologies that package the viral RNA into a bacteriophage, the AccuPlex recombinant virus releases the viral genome at a similar rate as that of wild-type mammalian pathogenic virus during the nucleic acid sample preparation step. AccuPlex recombinant virus material mimics a real clinical sample across the entire workflow, serving as a full-process control.

• Replication deficient with a flexible sequence design, as opposed to cultured virus options
• True full-process control with a complex viral structure, unlike MS-2 bacteriophage
