High-throughput, high-quality RNA purification for COVID-19 detection

COVID-19 testing protocols require fast, reliable, high-yield, high-quality and easily automatable, sample preparation methods. sbeadex™ viral RNA purification kits meet these requirements. For Research Use Only. Not for use in diagnostic procedures.

Key benefits

  • Qualified protocol for RUO COVID-19 assays  (qualified for research use only using SeraCare’s AccuPlex™ reference material)
  • Compatible with most popular robotic platforms, including the Kingfisher™ and our high-throughput oKtopure™ instrument
  • Fast – both short (25 min) and standard (45 min) protocols available
  • High sensitivity: 750 copies in 1 mL; 100% recovery rate
  • High-throughput batch sizes (5,000 purifications)
  • Water-based wash buffers reduce solvent carryover, resulting in absence of PCR inhibitors in final eluate
  • High-RNA-quality for all downstream applications including qPCR and PCR

Product info

sbeadex viral RNA purification kits are magnetic-bead based kits are validated for research use only using AccuPlex™ reference material (SeraCare), replicating a real-life clinical sample as far as practically possible, and are compatible with Biosearch Technologies’ COVID-19 detection kit. The sbeadex viral RNA isolation kit portfolio offers products for all scales of nucleic acid preparation from buccal swab and sputum samples, eluting into 100 µL buffer.

RNA preparation protocol

sbeadex beads allow efficient and high quality purification of small and large DNA fragments. The beads are double coated, resulting in a unique dual binding protocol that allows elution into water, reducing solvent carryover:

Figure 1:  Demonstration of no loss of RNA during the sbeadex viral RNA purification kit protocol.  500 copies of a 2019-COVID artificial RNA reference material were added to a sample (nasopharyngeal swab) and the sample processed with the sbeadex viral RNA purification kit. SARS-CoV-2 was detected in this preparation and a directly spiked positive control sample via a RT-qPCR at two separate Biosearch Technologies sites (reaction components described below). The concordant Cq values from both samples demonstrate no loss of sample due to the extraction step.
