NEXTflex™ PCR-Free Barcodes are barcoded adapters for multiplexing Illumina libraries which 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 PCR-Free Barcodes accomplish this by using an indexed adapter with a 6 nt unique sequence. This allows for proper differentiation between samples, preventing poor reads caused by single base errors introduced during PCR. The NEXTflex index is contained within the adapter sequence, eliminating the need to perform PCR to add flow cell binding sequences.
These barcodes can be used with single, paired-end, and multiplex reads and are compatible with the NEXTflex PCR-Free Sequencing Kits and other PCR-Free DNA library prep protocols.
