NxSeq® AmpFREE Low DNA Library Kit

NxSeq® AmpFREE Low DNA Library Kit

Description

The highest efficiency, low input, pcr-free fragment library prep kit available at the lowest cost.

  • Low Input: Requires as little as 75 ng of sheared input DNA allowing use of limiting samples.
  • High Efficiency: Optimized adaptor ligation produces more sequenceable fragments in each library, yielding better coverage & depth from single or multiplexed libraries.
  • PCR-free: Prevents the introduction of PCR-bias, providing more uniform coverage.
  • 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.

The NxSeq® AmpFREE Low DNA Library Kit allows you to build the best fragment DNA libraries possible. We optimized each step of the protocol to ensure peak performance on Illumina sequencers. In addition, these kits require only 75 ng of sheared DNA input, and produce libraries in about 2 hours using a streamlined, easy to follow protocol.

  • Minimal GC Bias

Lower Price 

Faster, Easier Protocol 


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.


Sequencing Impact of Higher Efficiency Library Construction

Better Libraries Increase the Number of Reads per Library


Figure 2a. Number of sequencing reads generated per library after multiplexing and running on a MiSeq Instrument. DNA fragment libraries were prepped in parallel for each kit/organism according to the manufacturer’s recommended input amounts and protocols. Libraries were quantitated and normalized to 2 nM using the Bioanalyzer (size) and Qubit Fluorometer (amount). Equimolar amounts of each library were multiplexed and sequenced with a single MiSeq run using 2 ×150 bp chemistry. The number of sequencing reads obtained are shown as well as the percent reduction (%) in total reads compared to the appropriate NxSeq AmpFREE Kit results.


More Proof with Challenging FFPE Samples


Figure 2b. Number of sequencing reads generated from matching normal and FFPE gDNA sample libraries. DNA fragment libraries were prepped using the two indicated kits according to the manufacturer’s recommended input amounts and protocols. Libraries were constructed from normal gDNA (Biochain, Cat. No. D1234142-S02) and DNA extracted from a matching FFPE human kidney tissue (Biochain Cat. No. T2234142-S02) using the Qiagen AllPrep DNA/RNA FFPE Kit. The gDNA samples were sheared to ~250 bp before starting library construction. Final libraries were quantitated and normalized to 2 nM using the Bioanalyzer (size) and Qubit Fluorometer (amount). Equimolar amounts of each library were multiplexed and sequenced with a single MiSeq run using 2 × 150 bp chemistry. The number of sequencing reads obtained are shown as well as the percent reduction (%) in total and mapped reads compared to the corresponding NxSeq AmpFREE Kit results using 75 ng of input DNA. 


Highly Mappable Reads (>92%) from Human, Staphylococcus and Rhodobacter gDNA Sequencing


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).
