OncoSpan is a well-characterized, cell line-derived Reference Standard containing over 380 variants across 152 key cancer genes.  Variants are present between 1-100% allelic frequency (AF), with 47 variants present at ≤ 20% AF for LOD determination of your assay. Every batch of OncoSpan DNA has 25 variants confirmed by ddPCR, in addition to being fully exome sequenced (Batches before 57404 were sequenced at 500x coverage on an Illumina platform using the Agilent SureSelect Human All Exon V6 kit. Batches from 57404 are sequenced at 500x coverage by Revvity Omics using the Agilent CREV3 kit and an Illumina platform). This provides you with an accurate and reliable truth set for comparison to your assay’s performance. You will receive a password upon ordering to download the raw NGS data for your batch (bam, bed and vcf files).  Alternatively, for your convenience we have also listed the 386 high confidence variants in an easy-to-access excel document that can be downloaded.
