NEXTFLEX® Rapid XP V2 DNA-Seq Kit for Illumina® Platforms

The new NEXTFLEX® Rapid XP V2 DNA-seq kit includes proprietary NEXTFLEX® normalization beads, which provide a consistent mass and sequencing cluster density for all samples in a library pool. This shortens the time needed for quantification and pooling preparation for sequencing in a high throughput lab by up to 3 hours per 96 samples.

Highly Efficient Ligation with Low Adapter Formation

The NEXTFLEX® Rapid XP V2 DNA-seq kit offers a streamlined workflow with highly efficient ligation, generating low amount of adapter dimers even at low input concentrations.

reduced dimer formation DNA-seq libraries
Figure 1. Low dimer formation with NEXTFLEX® Rapid XP V2 DNA-Seq kit. Different library replicates were prepared using either 500 pg (A) or 1 ng (B) of high-quality genomic DNA as input. Adapter dimer should appear as a peak at ~150 bp.
Reduced GC bias with DNA-seq libraries
Figure 2. Analysis of GC bias from libraries obtained with NEXTFLEX Rapid XP V2 DNA-Seq kit. Results show minimal variability in normalized coverage across 20-60% GC content encompassing ~95% of the human genome (Right: red bars). These are consistent across 1-750ng of genomic DNA input.

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

Barcodes are not supplied with the NEXTFLEX® Rapid XP DNA-seq kit v2 and need to be purchased separately. We offer 384 color-balanced NEXTFLEX® UDI adapters that improve multiplexing capabilities for both low-level and high-level multiplexing needs. Additionally, a set of 1,536 NEXTFLEX® UDI adapters which are compatible with the NEXTFLEX® Rapid XP DNA-seq kit v2 are now available for ultra high-throughput applications.
