Additional product information

Highest Sample Multiplexing Options for Illumina Sequencers

The design of the NEXTFLEX Unique Dual Index barcodes allow a broad range of multiplexing – users can multiplex anywhere between two samples and 1,536 samples in a single sequencing run. The wide range of multiplexing options enables barcode rotation (avoiding frequent use of the same barcode set) to mitigate run-to-run sample carryover and crosstalk. NEXTFLEX Unique Dual Index barcodes are compatible with NEXTFLEX library prep kits designed for paired-end and single-read sequencing, or other workflows for Illumina sequencers that involve the ligation of adapters to adenylated fragments.

Highest Level of Data Integrity

The NEXTFLEX Unique Dual Index barcodes utilize two unique indexes on each UDI adapter, with a hamming distance of at least three throughout the entire series to permit error correction. Each NEXTFLEX Unique Dual Index barcode comprises the entire flow cell binding site, sequencing primer binding site and index sequences, thereby making PCR enrichment optional. Patterned flow cells, such as those found on the Illumina NovaSeq^®, HiSeq^® 3000/4000, and HiSeq X platforms, have been known to suffer from increased rates of sample mis-assignment during sequencing. The use of adapters with unique dual indices improves data integrity by correctly removing mis-assigned reads. Every lot is tested for index purity and functionality by sequencing.

FAQs

Q: Are the NEXTFLEX unique dual index barcodes sequence-verified for purity?
A: Yes, each lot of the adapters undergoes stringent QC procedures that include verification of the index sequence purity by sequencing on an Illumina MiSeq instrument.

Q: Are the NEXTFLEX unique dual index barcodes functionally validated?
A: Yes, each lot of these adapters undergoes stringent QC procedures that include functional validation of the barcoded adapter by making a library.

Q: What is the lead time when I order the NEXTFLEX unique dual index barcodes?
A: They are in-stock and ready-to-ship.

Q: Why are the NEXTFLEX unique dual index barcodes only supplied at two reactions of each barcode in the 96-well plate?
A: The NEXTFLEX unique dual index barcodes are supplied in aliquots of two reactions of each barcode to reduce the potential for contamination, which increases with repeated use of the same plate.

Q: Must I perform paired-end sequencing with NEXTFLEX Unique Dual Index Barcodes?
A: No, they are compatible with paired-end and single-read sequencing runs. The I7 and I5 indexes are read in separate sequencing events than Read 1 and Read 2.

Q: Can I use the NEXTFLEX Unique Dual Index Barcodes in single index experiments?
A: Yes, you can configure your sequencing run to only read the I7 index when you set up the run.
