Reproducible library fragment size distributions are obtained with different DNA inputs. Various input amounts of Escherichia coli gDNA were processed using the KAPA HyperPlus Kit with fragmentation times of 15 or 30 minutes at 37ºC. After library amplification and a single bead cleanup, samples were analyzed using an Agilent® High Sensitivity DNA Assay.

Defined fragmentation parameters yield consistent library insert sizes for samples from multiple species across a wide range of GC content. 10 ng or 50 ng of Bordetella pertussis (68% GC), Clostridium difficile (29% GC), Escherichia coli (51% GC), Plasmodium falciparum (20% GC) or human gDNA were fragmented for 5, 15 or 45 minutes. These fragmentation times yielded average library insert sizes of approximately 700 bp, 350 bp and 200 bp, respectively; irrespective of GC content and input amount. All fragmentation reactions were performed at 37ºC.

Industry-leading library yieldsHigh conversion rates, defined as % input DNA converted to sequenceable, adapter-ligated library, lead to higher PCR-free yields, which ultimately determines library diversity and quality.
• Low-input samples no longer require specialist library construction workflows or reagents
• PCR-free workflows possible from as little as 50 ng starting material
• Both the existing and upgraded KAPA HyperPlus chemistry produce the highest post-ligation yields
Enable superior sequencing results• Higher post-ligation yields result in fewer amplification cycles and lower duplication rates
• Detect low-frequency mutations with high confidence due to decreased sequencing artifacts and increased sensitivity with the upgraded version of the KAPA HyperPlus Kit
KAPA HyperPlus Kits produce the highest yields from a range of input amounts. The KAPA HyperPlus Kit (both existing and upgraded workflows) converts more input DNA to adapter-ligated library than NEBNext® Ultra II FS Kits or Covaris shearing combined with KAPA HyperPrep. PCR-free libraries were prepared from 1 ng, 10 ng and 100 ng E.coli gDNA using KAPA UDI Adapters and KAPA HyperPure Beads for all workflows, including NEBNext Ultra II FS Kits. Libraries were quantified after ligation using the KAPA Library Quantification Kit.
Input Amount
* KAPA HyperPlus (existing) represents the use of the HyperPrep End Repair & A-Tailing Enzyme Mix (original enzyme); KAPA HyperPlus (upgraded) represents the use of the HyperPlus End Repair & A-Tailing Enzyme Mix (a new enzyme that is now included in the KAPA HyperPlus Kit).
Lower duplication rates. Whole human exome libraries were prepared using 100 ng inputs with the exisiting and upgraded KAPA HyperPlus Kit, or the KAPA HyperPrep Kit. Captures were performed with the SeqCap EZ MedExome panel.
Improved sequencing performance. Whole human exome libraries were prepared using 100 ng inputs with the existing and upgraded KAPA HyperPlus Kit. Captures were performed with the SeqCap EZ MedExome panel. Strand-split artifact reads (SSARs) represent chimeric reads that appear to be derived from non-contiguous portions of the genome.1
Higher single nucleotide polymorphism (SNP) sensitivity. Whole human exome libraries were prepared using 100 ng high-quality gDNA with the KAPA HyperPrep Kit, the existing and upgraded KAPA HyperPlus Kit. Captures were performed with the SeqCap EZ MedExome panel.

GC bias comparison. GC bias for C.difficile (left), E.coli (middle) and B.pertussis (right) was assessed by calculating the GC content of the reference in 100 bp bins and plotting normalized coverage across these bins for the KAPA HyperPlus, NEBNext® Ultra™ FS and QIAseq FX workflows, using Picard CollectGCBiasMetrics. Libraries were prepared from 10 ng of input DNA. In the absence of sequencing bias, all bins would be equally represented, indicated by a horizontal distribution centered on a normalized coverage of 1. Distribution of GC content in the genome is indicated by the grey histograms.
