Preparation of Multiplexed Amplicon Libraries

The NEXTFLEX® 16S V1 – V3 Amplicon-Seq Library Prep Kit is designed for the preparation of multiplexed amplicon libraries that span the hypervariable domains one through three (V1-V3) of microbial 16S ribosomal RNA (rRNA) genes. These libraries are compatible with paired-end sequencing on the Illumina® MiSeq® sequencing platform.

Fast Library Prep Protocol

There are two main steps involved in 16S V1-V3 amplicon processing: an initial PCR amplification using customized PCR primers that target the V1-V3 domains, and a subsequent PCR amplification that integrates relevant flow cell binding domains and unique 12 base pair sample indices. The limited number of cleanup steps ensures maximum recovery of amplicons for downstream sequencing.

Optimized Protocol Offers Lower PCR Bias and Fewer Off-target Reads

The protocol incorporated in the NEXTFLEX 16S V1 – V3 Amplicon-Seq Kit offers better sequencing results than can be obtained using traditional 16S sequencing protocols. The incorporation of the second PCR step in the protocol for the addition of the sample-specific index reduces the number of off-target reads typically encountered during amplicon sequencing.

The NEXTFLEX 16S V1 -V3 Amplicon-Seq Kit contains enough material to prepare 8, 24, 96 or 192 amplicon-seq libraries from genomic DNA for Illumina® sequencing. The shelf life of all reagents is 12 months when stored properly. All components can be safely stored at -20°C. This kit is shipped on dry ice.

Outside of novel sequencing technologies that emerge every few years, the ability to multiplex samples is the most critical and revolutionary aspect of next-generation sequencing. Multiplexing allows for acute control of throughput, amplifying the value of obtaining just enough data per sample.

To make multiplexing possible, small arbitrary sequences are incorporated into the sequencing adapters attached to all fragments of a particular sample. These sequences, known as barcodes, allow for post-sequencing processing to bin each fragment by its originating sample.

However, even high-fidelity polymerases used during sequencing reads are invariably prone to introducing errors. These errors are especially costly when landing during the barcode read, preventing proper binning and wasting associated sequencing reads. To alleviate this, the knowledge of bitwise error correction was extended to the base-wise language of sequencing.

The overall ability to correct barcode read errors stems from the differentiability between the entire set of barcodes. Differentiability can be called distance, or the number of single position changes that are required for one barcode sequence to become another. For example, the top sequence in the below figure has only one position change from the middle, while the middle has one position change from the bottom. Overall, the top to bottom sequence requires two position changes. This concept, known as the Hamming distance, is what powers barcode error correction and casual codebreaking games like Mastermind.

16s-v1-v3-tip-figure-1

The greater the minimum distance separation across an entire barcode set, the stronger the differentiability. This in turn governs how many errors can be error-corrected across a barcode subset. Maximum error correction is governed by the following formula:

16s-v1-v3-tip-figure-2

where d is the minimum distance across the entire set.

How does minimum distance affect generating barcode sets? By increasing the minimum distance across a subset, the overall maximum subset size decreases. One must set requirements so that sufficient barcodes are within a set of desired error correction.

We have expanded previously available barcode sequence sets in both set size and index lengths to accommodate higher levels of error correction. Also, other factors such as colorspace on Illumina instruments have been considered, leaving customers with a minimal amount of effort in selecting the best subsets for low-diversity sequencing runs.

Our new 12 nt barcode set, available with the NEXTFLEX® 16S V1 – V3 Amplicon-Seq Kit, allows for up to two error corrections and has multiple low-diversity pooling options. We will continue to develop new technologies to remain the leader in quality multiplexing options.
