Improved GC coverage with Solaris 2.0
Ultima integrates enhanced sequencing amplification chemistry with flexible library preparation options, including both PCR-free and indexing PCR workflows. Together, these improvements reduce GC bias and improve coverage uniformity across the genome. The data shown here were generated using the Solaris 2.0 PCR-free library workflow.
Download WGS Application NoteAccurate variant calling across genome
Variant calling performance was assessed in comparison to reference GIAB truth sets, using the full NIST HCR v4.2.1 for each reference sample unless otherwise noted. The overall average concordance of single nucleotide polymorphism (SNP) variant calls over the dataset was F1 = 99.79%, and for Indel variant calls (excluding homopolymers ≥ 12) was F1= 99.06%. Variant calling in coding regions returned SNP F1 = 99.60% and Indel F1 = 98.84%.
Clinically Relevant Gene Coverage
The improvement in high-GC coverage translates into more consistent depth across GC-rich, clinically relevant loci that are traditionally challenging for short-read sequencing workflows. By reducing dropout and uneven amplification in these regions, Solaris 2.0 enables more reliable variant detection, improved confidence in calling across promoter regions and GC-dense exons, and stronger performance in genes associated with inherited disease and oncology applications.
