NEXTflex™ PCR-Free Barcodes 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 PCR-Free Barcodes Kits accomplish this by using an indexed adapter with a 6 nt unique sequence. This allows for proper differentiation between samples, preventing poor reads from 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. For larger volume requirements, customized and bulk packaging is available. Please contact firstname.lastname@example.org for further information.
