Decrease your cost-per-sample with multiplex sequencing
Our multiplexing options allow large numbers of sample libraries to be pooled and sequenced simultaneously on a SMRT Cell. Sample multiplexing is useful when targeting specific genomic regions or working with smaller genomes.
Samples are barcoded by incorporating PacBio-specific barcodes to both ends of the double-stranded DNA so that reads can be identified and sorted before data analysis. Barcodes are located between the hairpin adapters and sample insert.
Multiplexing is supported with three options that provide flexibility to incorporate unique sample identifiers, called barcodes, during target amplification or library preparation. This is achieved through barcoded primers for single-step PCR, tagged barcoded primers via two-step PCR, and barcoded overhang adapters.
Setting up multiplexing on Sequel, Sequel II, and IIe systems
Barcoding strategies for multiplexing on PacBio Sequel systems are application dependent. All workflows can include barcodes to uniquely identify samples but differ in how barcodes are incorporated into the SMRTbell templates. List of recommended barcodes, procedures, ordering sheets and FASTA files required for demultiplexing are listed below, by application.
Whole genome sequencing
As the throughput of PacBio Sequel systems has increased, so has a corresponding growth in multiplexing capacity for whole genome sequencing, specifically for microbial sequencing, de novo assembly and structural variation.
