Prevent Poor Reads Caused by Single Base Errors

The NEXTFLEX® DNA barcodes for Ion Torrent sequencing platforms can be used to provide flexibility and high-throughput capabilities in sequencing applications. They significantly increase scale while reducing costs by allowing the user to pool multiple library preparations in a single flow cell lane. The NEXTFLEX® DNA barcodes use an indexed adapter with a 10 nt unique sequence, allowing for proper differentiation between samples and preventing poor reads caused by single base errors introduced during PCR. Up to 64 samples can be multiplexed using these adapters. The NEXTFLEX® DNA barcodes undergo stringent quality controls and are functionally validated by sequencing.

These barcodes are compatible with the NEXTFLEX® DNA library prep kits for Ion Torrent sequencers, the NEXTFLEX® Cell Free DNA-seq kit for Ion Torrent sequencers, and other genomic and ChIP-seq DNA library prep protocols compatible with the Ion Torrent PGM, Ion Proton, Ion S5, and Ion S5 XL sequencers.

For larger volume requirements, customized and bulk packaging is available. Please contact [email protected] for further information.
