Key Performance Data
Enhanced library conversion, enabling high-quality sequencing data.
(A). Enhanced library conversion efficiency with Yeasen DNA Library Prep Kit, delivering higher library yield from low-input DNA.
(B). Ultra-low adapter dimer formation, demonstrating minimal self-ligation even with as little as 0.5 ng gDNA input.
Compared with multiple commercial ligases, Yeasen’s ligation chemistry showed minimal adapter self-ligation and the lowest adapter dimer formation at 0.5 ng gDNA input, enabling high-quality libraries from ultra-low DNA amounts.
Low fragmentation and GC bias ensure uniform coverage
(A). Cleavage-site preference analysis.
Base-quality window analysis (30 bp, Read 1 and Read 2) showed that Yeasen random endonuclease–based fragmentation has lower sequence bias than the Tn5 transposase method and produces profiles closer to ultrasonic fragmentation.
(B). Reduced sequence artifacts enables high-sensitivity applications.
Library preparation using 200 ng NA12878 gDNA showed that the Yeasen 12194ES kit produced a lower percentage of adapter self-ligation and mismatched reads compared with supplier K* and V*.
Reduced ligation- and fragmentation-associated artifacts improve data accuracy and enhance confidence in sensitive applications, including low-allele-frequency variant detection.
Reduced artifacts improved data quality and supported more accurate SNP and InDel detection, reflected by slightly higher F-measure scores compared with competing kits.
(C). GC bias analysis using 1 μg NA12878 DNA (30 °C, 10 min enzymatic fragmentation; PCR-free library; PE150 sequencing, 30×, 90 Gb data) showed consistent coverage across both low-GC and high-GC regions, demonstrating uniform performance across genomes with GC contents ranging from 30% to 75%.
