NxSeq¢ç AmpFREE Low DNA Library Kits and Adaptors (Illumina-compatible)
The highest efficiency NGS fragment library prep kit available at the lowest cost
- Great Performance: High efficiency libraries mean more sequenceable fragments in each library, better coverage & depth from single or multiplexed libraries which improves confidence in each sequencing run.
- Minimal Bias: PCR-free DNA libraries produce more uniform coverage from as little as 75 ng of sheared input DNA.
- Fast: 2 hour, 10 minute protocol saves you time and gets your samples on the sequencer sooner.
- Affordable: Best priced and best performing kit available.
Higher Efficiency Libraries
More Sequenceable DNA Fragments per Library = More Data
Figure 1. Percentage of library DNA with correctly ligated adaptors measured by qPCR. Duplicate libraries were prepped per kit/organism (Human, Staphylococcus aureus, Rhodobacter sphaeroides (1 library only), and E. coli) according to the manufacturer¡¯s recommended input amounts and protocols. Adaptor ligation efficiency was measured by qPCR using the KAPA Library Quantification Kit (Complete ROX Low, cat #KK4873) and matching amplified library as an internal standard.
Greater Percentage of Identifiable Clusters
More DNA Fragments Sequenced per Run = More Data
Figure 2. Percentage of clusters identified upon sequencing various library prep kits. Prepped each library per kit/organism (Human, Staphylococcus aureus, Rhodobacter sphaeroides, and E. coli) according to the manufacturer¡¯s recommended input amounts and protocols. Quantitated and normalized samples to 2 nM final concentrations using the Bioanalyzer and Qubit fluorometer. Ran 5 µL of each sample on a MiSeq using 2 x 150 bp chemistry.

Figure 3. Representative gDNA sequencing stats from three different organisms. Genomic DNA fragment libraries were generated using the NxSeq AmpFREE Low DNA Library Kit using 75 ng of sheared gDNA input from three organisms (human, Staphylococcus aureus, and Rhodobacter sphaeroides). The final libraries were quantitated and normalized to 2 nM final concentrations using the Bioanalyzer and Qubit fluorometer, and 5 µL of each library was run on a MiSeq using 2 x 150 bp chemistry and analyzed.
Minimal Bias Detected
Figure 4. Sequencing bias measured for three different organisms with varying GC content. DNA fragment libraries were generated from gDNA of three organisms with varying GC content (Staphylococcus aureus, 24% GC; E. coli K12, 50% GC; and Rhodobacter sphaeroides, 68% GC) according to the manufacturer¡¯s recommended input amounts and protocols. Samples were quantitated using the Bioanalyzer and Qubit fluorometer and normalized to 2 nM final concentrations. Five µL of each library sample was sequenced on a MiSeq using 2 x 150 bp v2 chemistry and analyzed. Normalized coverage was calculated as the (average coverage of all windows with X% GC content) divided by the (overall average coverage).
