Rapid DNA Library Prep for Sequencing on Illumina® Platforms

The NEXTFLEX® rapid DNA-seq 2.0 kit is designed to prepare multiplexed libraries for single or paired-end sequencing using Illumina® platforms. The enhanced NEXTFLEX® kit simplifies workflow by using master mixed reagents and magnetic bead based cleanup, reducing pipetting and eliminating time-consuming steps in library preparation. The NEXTFLEX® rapid DNA-seq kit produces library preps with a larger number of unique sequencing reads, allowing for robust genome coverage in challenging GC-rich sequences that can introduce bias.

The NEXTFLEX® rapid DNA-seq 2.0 kit bundle offers all the advantages and reagents of the core kit, but with the additional benefit of including unique NEXTFLEX-HT barcodes for the number of reactions (8, 48, or 96 reaction size kits) in a single-use format. This allows the lab to tie all the necessary components of the library prep workflow to a single lot for ease of purchasing and tracking of consumables.

Flexible Multiplexing Options

The NEXTFLEX® adapters are long, annealed adapters containing indexed sequences, which offer an improved multiplexing workflow and flexible experimental setups catered to individual needs. Our barcode portfolio encompass options for single or paired-end multiplex sequencing, and the NEXTFLEX® rapid DNA-seq kit 2.0 is compatible with the NEXTFLEX® DNA Barcodes and NEXTFLEX-96 DNA BarcodesNEXTFLEX® ChIP-Seq Barcodes, and NEXTFLEX-96 ChIP-Seq Barcodes. The NEXTFLEX® rapid DNA-seq kit 2.0 reagents are also compatible with the NEXTFLEX® Unique Dual Index Barcodes  for up to 192 sample multiplexing.

The NEXTFLEX® rapid DNA-seq kit 2.0 bundles come provided with the NEXTFLEX-HT Barcodes.
