Product Details
The MagAttract Viral RNA Kit combines the speed and efficiency of silica-based nucleic acid purification with the convenient handling of magnetic particles. A well-established technology is used for viral RNA preparation in a 96-well format. The purification procedure is designed to ensure reproducible handling and comprises four steps: lyse, bind, wash and elute.
Principle
The MagAttract Viral RNA Kit provides fully automated purification of viral RNA from respiratory swab samples. MagAttract technology combines the speed and efficiency of silica-based RNA purification with the convenient handling of magnetic particles. Samples are processed in the KingFisher Flex Workdeck. No phenol–chloroform or manual column extraction is required.
Procedure
In the automated workflow, viral RNA binds specifically to the magnetic beads while contaminants such as divalent cations and proteins, are completely removed in three efficient wash steps. High-quality RNA is eluted in a special RNase-free buffer, ready for direct use or safe storage. The purified RNA is free of proteins, nucleases, and other contaminants or inhibitors and can be used immediately in demanding downstream applications, including PCR, qPCR, dPCR and next-generation sequencing. Protocols are available for use on the Thermo Scientific KingFisher Flex. This kit can also be used with many other automated handling systems.
Carrier RNA
Carrier RNA serves two purposes: First, it enhances binding of viral nucleic acids to the magnetic beads, especially if there are very few target molecules in the sample. Secondly, the addition of large amounts of carrier RNA reduces the chance of viral RNA degradation in the rare event that RNase molecules escape denaturation. Not adding carrier RNA to Buffer ACL may lead to reduced viral RNA recovery.
Applications
The high-quality RNA obtained using the MagAttract Viral RNA Kit and the Thermo Scientific KingFisher Flex platform is suited for use in many downstream applications, such as:
- Viral epidemiology and genotyping
- Infectious disease research
