Overview

  • Up to 1,536 unique i5 / i7 pairs (10NT) ready to ship
  • Compatible with PCR-free and PCR-amplified workflows
  • ≥ 3-base Hamming distance across the entire set for robust error-correction and balanced base diversity on 2- & 4-color chemistries
  • Designed to minimize index hopping that can be present with patterned flow cells.
  • Compatible with Revvity library prep and TruSeq style, ligation-based workflows
  • Every lot is functionally validated and tested for index purity by sequencing in an ISO 9001 facility
  • Optional NEXTFLEX Universal Blockers boost on-target hybrid-capture efficiency when used with these UDIs.

Additional product information

NGS Multiplexing Performance

Scale from 2 to 1,536 libraries in a single NovaSeq® (Illumina) or AVITI® (Element)flow cell. The 10NT UDI set supports barcode rotation between runs, eliminating carry-over and virtually stopping index hopping on patterned flow cells. Adapters work out-of-the-box with all TruSeq-style library-prep kits, including NEXTFLEX, Illumina, Watchmaker, Twist library prep kit s, whether PCR-free or PCR-amplified.

“Revvity has a set of 1536 validated UDI adapters that we have been regularly using for 5 years. Using the Illumina® NovaSeq® X Plus with this UDI set from Revvity we can sequencing 12,288 samples across 8 lanes of the 10B or 25B flow cells.  This dramatically lowers our sequencing cost per sample!”

-Dr. Charlie Johnson, Director of Texas A&M Agri Life Genomics and Bioinformatics Service

NGS Adapters with High Data Integrity

Each NEXTFLEX UDI adapter has a dedicated 10NT i7 & i5 sequence separated from every other pair by a ≥ 3-base Hamming distance, enabling single-base error correction during demultiplexing. Because the adapter already contains the full flow-cell and primer-binding sites, PCR enrichment is optional. On patterned flow cells (Illumina NovaSeq®, HiSeq® 3000/4000, HiSeq® X, Element AVITI™) the use of true, unique dual indexes cuts index-hopping artefacts to background levels by removing mis-assigned reads. Every lot is sequenced for ≥ 99.9 % index purity and functional ligation efficiency, ensuring data integrity run after run.
