NanOnCT Panel v1.0 is a compactable panel designed for analysis of solid tumors and liquid biopsy. This panel involves a total number of 69 genes with selected regions covered. With an optimized probe design, this panel offers a highly uniform coverage over targeted regions for both FFPE and cell-free DNA.

The DNA libraries were prepared using NadPrep library kits with 50 ng of human genomic DNA (Promega, G1512) and 10 ng of plasma cfDNA from a healthy donor, respectively. 1 M read pairs were subsampled for the analysis. On-target rates were calculated as the percentage of mapped read pairs that overlap with probe regions.
Coverage Uniformity

Variant Analysis
Fig 2. Evaluation of NanOnCT Panel v1.0 on the analysis of SNVs and indels. DNA libraries were prepared from Onco SNV Multiplex 1-25% gDNA (Genewell, GW-OGTM004) using NadPrep library kits. The enriched libraries were sequenced either on HiSeq X Ten (PE150) or DNBSEQ-G400 (PE100).

The DNA libraries were prepared from Onco Structural Multiplex 5% gDNA (GeneWell, GW- OGTM001) using NadPrep library kits. The libraries were enriched using the NanOnCT Panel v1.0. The enriched libraries were sequenced either on HiSeq X Ten (PE150) or DNBSEQ-G400 (PE100).
Coverage Over Selected Microsatellite Markers
