CleanPlex for MGI SARS-CoV-2 Panel for COVID-19 coronavirus detection, tracking, and research via amplicon-based target enrichment for Next Generation Sequencing (NGS) on MGI Tech’s DNBSEQ platforms
Paragon Genomics designed a highly multiplexed target enrichment panel covering the entire genome of SARS-CoV-2 virus (except for 92 bases at the ends). The panel enables complete genome sequencing and epidemiological studies of the new SARS-CoV-2 virus responsible for the COVID-19 pandemic. With Paragon Genomics CleanPlex technology, the entire genome of the virus can be amplified from RNA to sequence-ready libraries in 5 hours. Two versions of this the panel are available for two major sequencing platforms: Illumina and MGI. CleanPlex Technology allows the ease and flexibility to sequence samples for confident infectious disease surveillance and research.
Significant Cost Savings 98% reduction in sequencing cost. Only 0.2M reads per sample required v.s. 10M reads required by many shotgun metagenomics sequencing methods.
High Coverage of Target Regions 99% coverage of the entire SARS-CoV-2 genome
Sensitive Detection Can detect down to 1 copy with high confidence compared 3-5 copies by RT-qPCR (1)
Fast, Streamlined Workflow Generate sequencing-ready libraries in just 5.5 hours using a rapid, four-step protocol including RT step with minimal hands on time.
Superb Performance Prepare high-quality NGS libraries with excellent on-target performance using CleanPlex Technology to enable efficient use of sequencing reads. CleanPlex panels’ on-target rates are usually much higher than those of hybrid captured-based small target enrichment panels.
The CleanPlex SARS-CoV-2 Panel contains the CleanPlex Multiplex PCR Primers and CleanPlex Targeted Library Kit with RT components. CleanPlex Indexed PCR Primers and CleanMag Magnetic Beads are ordered separately to complete the workflow from input RNA to sequencing-ready NGS libraries.

(Left) Using plasmids containing the N and S genes of SARS-CoV-2 on with a single pool workflow for detection, the detection rate at low copy numbers are show. The detection rate was shown to be 56% at 1.1 copy and 100% when more than 2 copies were present. With the use of both pools to cover the entire viral genome, the sensitivity is expected to only further increase. (Right) For these detected, the panel was able to on average capture all targets within 10 fold read depth range for 2.8 viral copies, and similarly for all but one target for 1.4 viral copies. All targets were also uniformly distributed across the GC range.

CleanPlex is the the most advanced PCR amplicon sequencing technology.
What is Targeted Sequencing (Resequencing) / Target Enrichment? During Target Enrichment, the target DNA sequences are either directly amplified (amplicon or multiplex PCR-based) or captured (hybrid capture-based) and then subsequently sequenced using DNA sequencers. This process is followed by Targeted Sequencing, also known as Resequencing, where only the region of interest containing the target DNA is sequenced instead of a whole genome.
Why Target Enrichment? Whole genome sequencing (WGS) and its corresponding whole genome amplification (WGA)’s applications are more suited for research and discovery. While Targeted Sequencing and Target Enrichment are preferred in a fast-growing clinical and industrial context where cost and speed are key.
CleanPlex NGS Target Enrichment Amplicon Sequencing Technology CleanPlex technology is an ultra-high multiplex PCR amplicon-based target enrichment technology for NGS targeted sequencing (amplicon sequencing as opposed to hybrid capture-based sequencing). It features a highly advanced proprietary primer design algorithm, an exceptionally uniform multiplex PCR amplification chemistry and an innovative, patented background cleaning chemistry. Together, they allow CleanPlex Ready-to-Use and Custom NGS Panels to break the limits of existing PCR amplicon-based and hybrid capture-based target enrichment technologies.
High accuracy with lower sequencing cost: super high amplification uniformity and super low PCR background noise
Easily automated: single-tube and 3-hour workflow with minimal hands-on time
High compatibility: suited for difficult samples (degraded FFPE, cfDNA) and major sequencing platforms (Illumina, Ion Torrent, MGISeq)
Extreme sensitivity: down to single cell level direct amplification
Excellent panel size scalability from a few amplicons to over 20,000 amplicons in a single multiplex PCR pool
CleanPlex multiplex PCR-based NGS target enrichment workflow. CleanPlex Ready-to-Use and Custom NGS Panels allow high-quality target-enriched NGS libraries to be easily and quickly prepared for amplicon sequencing.
CleanPlex background cleaning chemistry. The CleanPlex chemistry’s streamlined protocol can be completed with 3 simple steps, each consisting of a thermal cycling or incubation reaction followed by a library purification using magnetic beads.
Step 1: targets of interest are amplified in a multiplex PCR reaction. Step 2: primer-dimers, non-specific PCR products, and complex molecular-debris are biochemically removed in a digestion reaction. Step 3: libraries are barcoded with sample indexes and amplified in a PCR reaction.
High performance powered by background cleaning Non-specific PCR products and primer-dimers are biochemically removed using the proprietary CleanPlex digestion chemistry. This ensures that only DNA sequences of interest are converted into NGS library molecules, resulting in highly efficient use of sequencing reads.
Effective removal of PCR background. Libraries were prepared using the CleanPlex OncoZoom Cancer Hotspot Panel with (blue trace) or without (red trace) using the CleanPlex digestion reagent and examined using an Agilent® Bioanalyzer®. Without CleanPlex digestion, significant PCR background was formed, which would result in low mapping rate and poor on-target rate and require more sequencing reads to obtain adequate data. With CleanPlex digestion, nearly no background was generated, producing a sharp and clean library peak in the Bioanalyzer trace. The proprietary CleanPlex digestion chemistry is essential for removing undesired side products formed during multiplex PCR amplification of target sequences.
