  • Barcoded PCR Primers for multiplexing contain embedded index sequence
  • Up to 48 multiplexed samples
  • Considerably reduce your per-sample sequencing cost by barcoded multiplexing
  • Increase your sequencing scale by pooling 100s of samples on a single flow cell
  • Compatible with Illumina® platforms

Note: these barcoded primers are provided in the NEXTflex Small RNA-Seq Kit v3 and do not need to be purchased separately.

Four sets of 12 NEXTflex™ Small RNA Barcode Primers, with embedded index sequences are available offering an improved multiplexing workflow and increased flexibility. This automation-friendly format enables multiplexing of up to 48 samples. The ability to pool samples in an efficient way significantly decreases hands on time while providing robust data quality. The primer barcoding system utilizes a 6 nt index to differentiate up to 48 different samples on a single flow cell lane.

48 barcoded primers are divided into 4 different kits (A-D) containing 12 unique barcodes for multiplexing. Each set of NEXTflex Small RNA Barcodes Primers contains 96 reactions worth of barcodes.
