Figure 1. Percent bases covered by at least 30x across some of the key genomic databases such as Ensembl, RefSeq and CCDS, based on a January 2024 snapshot. KAPA HyperExome V2 Probes deliver better database coverage compared to vendors I, A and T that are leaving more “blind” spots, which may lead to repeats or need for spike-in probes. Vendor sample prep protocols were followed with singleplex 4h hybridizations for vendor I (3 replicates, NA12878), 8-plex o/n hybridizations for vendor A (48 data points from 6 replicate captures of 16 coriell DNAs), 8- plex o/n hybridizations for vendor T (72 data points from 16 coriell and 24 blood extracted DNAs). For KAPA HyperExome V2 Probes the KAPA HyperCap Evolved Workflow v4 was followed. A total of 40 libraries were prepared with the KAPA EvoPrep Kit and 40 libraries with the KAPA EvoPlus V2 Kit starting from 100 ng of blood extracted DNA samples (in 2 x 16-plex hybridizations) and from 100 ng of NA12878 DNA samples (in 4 x 1-plex hybridization and 4 replicates from an 8-plex hybridization). KAPA HyperExome V2 Probes enriched libraries were sequenced on a NovaSeqTM 6000 System at 2 x 100 bp and 60 M high-quality reads were analyzed per library. Vendor-enriched libraries were sequenced proportionally to their capture target size.
