The NEXTFLEX® Rapid XP DNA-Seq kit combines enzymatic fragmentation with end-repair and A-tailing in one reaction to create a highly efficient first step in library generation, which is followed by ligation and PCR (optional for PCR-free workflows). This effective one-tube workflow produces DNA-seq libraries with consistent library size, high yield, low GC-bias, and high coverage.


Simplify Library Construction with Pre-Plated NEXTFLEX® Rapid XP DNA-seq Kits

Pre-plated NEXTFLEX® library prep kits eliminate the need for plate set-up, offering preprogrammed library construction on the Sciclone® G3 NGS/NGSx, Sciclone® G3 NGSx iQ™ and Zephyr® G3 NGS workstations. Pre-plated kits allow labs to:

  • Save time spent on manual set-up and reduce overall library prep time

  • Reduce the chance for human error

  • Remove inefficiencies due to dead volume


Flexible Multiplexing Options with 1,536 Barcodes Available for High-Throughput Multiplexing

We offer a broad range of color-balanced NEXTFLEX® adapters that improve multiplexing capabilities for both low-level and high-level multiplexing needs. A set of 1,536 NEXTFLEX® UDI adapters which are compatible with the NEXTFLEX® Rapid XP DNA-seq kit are now available for ultra high-throughput applications.


The NEXTFLEX® Rapid XP DNA-seq kit is also compatible with NEXTFLEX® DNA Barcodes, NEXTFLEX-96™ DNA Barcodes, NEXTFLEX® ChIP-Seq Barcodes, and NEXTFLEX-HT™ barcodes.


Barcodes are not supplied with the NEXTFLEX® Rapid XP DNA-seq kit and need to be purchased separately.


产品特点:

  • Reliable: Consistent yields and high-quality sequencing metrics

  • Convenient: Kit includes fragmentation enzyme, cleanup/size selection beads, and conditioning solution to improve the fragmentation efficiency for DNA stored in buffers containing EDTA

  • Streamlined: Single step for fragmentation, end-repair, and adenylation with minimal hands-on time

  • Flexible: Up to 1,536 color-balanced NEXTFLEX® barcodes, allowing a wide range of multiplexing, are available separately

  • Efficient: Pre-plated version available for easier automation on the Sciclone® G3 NGS/NGSx and the Sciclone® G3 NGSx iQ™ workstations

Alternative FFPE Input Protocol

The NEXTFLEX® rapid XP DNA-seq kit protocol has been performance-validated using quality gDNA. The kit can also accommodate FFPE samples using an alternative protocol. Note that the user should verify quality of FFPE material prior to use with the kit. In order to prepare a library from FFPE samples, the following basic FFPE protocol can be followed.

Alternative Low Input Protocol

The NEXTFLEX® rapid XP DNA-seq kit protocol has been performance-validated using quality gDNA down to 1 ng. The kit can also accommodate low input sample down to 100 pg using an alternative protocol. Note that the user should verify quality of starting material prior to use with the kit. In order to prepare a library from low input samples, the following basic low input protocol can be followed.

Streamlined Enzymatic Fragmentation and Library Prep Workflow for Illumina® Sequencing

The NEXTFLEX® Rapid XP DNA-Seq kit combines enzymatic fragmentation with end-repair and A-tailing in one reaction to create a highly efficient first step in library generation, which is followed by ligation and PCR (optional for PCR-free workflows). This effective one-tube workflow produces DNA-seq libraries with consistent library size, high yield, low GC-bias, and high coverage.


The kit includes all the required reagents for fragmentation, library prep, and magnetic bead-based cleanup, and it is compatible with your NEXTFLEX® barcodes of choice. This DNA-seq library prep kit is highly flexible in terms of sample requirements, accommodating a range gDNA input amounts from 1 ng to 1 µg to quickly and efficiently generate high-quality libraries for Illumina® sequencing.

Figure 1: Reliable performance of NEXTFLEX® Rapid XP DNA-seq fragmentation enzyme.  DNA is fragmented more evenly and into smaller sizes using the NEXTFLEX® Rapid XP DNA-seq kit than Competitor K’s kit. Each dot indicates each library peak size. (A) Libraries were prepared from 1 µg of DNA with 7 minutes of fragmentation with 2 PCR cycles: NEXTFLEX® Rapid XP DNA-seq kit (484 ± 52 bp, 11 %, n=17), Competitor K’s kit (1266 ± 451 bp, 36 %, n=17). (B) Libraries were prepared from 100 ng of DNA with 8 minutes of fragmentation with 5 PCR cycles: NEXTFLEX® Rapid XP DNA-seq kit (457 ± 12 bp, 3 %, n=18), Competitor K’s kit (730 ± 119 bp, 16 %, n=17). (C) Libraries were prepared from 1 ng of DNA with 15 minutes of fragmentation with 12 PCR cycles: NEXTFLEX® Rapid XP DNA-seq kit (448 ± 54 bp, 12 %, n=17), Competitor K’s kit (628 ± 160 bp, 25 %, n=17). All different input libraries were generated from 6 different commercially available DNA samples. (mean ± standard deviation, coefficient of variation)


Conditioning Solution included with the kit for DNA samples stored in EDTA

EDTA reduces the efficiency of enzymatic fragmentation. Since DNA is frequently eluted and stored in TE (10 mM Tris, 1 mM EDTA) or other buffers containing EDTA, the NEXTFLEX® Rapid XP DNA-Seq kit now includes a Conditioning Solution to improve the fragmentation efficiency of these DNA samples without disrupting the workflow.

Figure 4. Libraries prepared with the NEXTFLEX® Rapid XP DNA-seq kit show less or comparable GC-bias than libraries prepared with Competitor K’s kit. Picard GC bias analysis, which show read coverage over the indicated genome with respect to GC content, is shown as a fraction of normalized coverage (blue) calculated in 100 bp windows (red) and plotted against the left y-axis. Mean base quality at each window (green) is calculated and plotted against the right y-axis.
