Illumina sequencing technology, sequencing by synthesis (SBS), is a widely adopted next-generation sequencing (NGS) technology worldwide, responsible for generating more than 90% of the world's sequencing data.1 Illumina sequencing instruments and reagents support massively parallel sequencing using a proprietary method that detects single bases as they are incorporated into growing DNA strands.
A fluorescently labeled reversible terminator is imaged as each dNTP is added, and then cleaved to allow incorporation of the next base. Since all 4 reversible terminator-bound dNTPs are present during each sequencing cycle, natural competition minimizes incorporation bias.2
The end result is true base-by-base sequencing that enables accurate data for a broad range of applications. The method virtually eliminates errors and missed calls associated with strings of repeated nucleotides (homopolymers).
Illumina sequencing by synthesis technology supports both single-read and paired-end libraries. SBS technology offers a short-insert paired-end capability for high-resolution genome sequencing, as well as long-insert paired-end reads for efficient sequence assembly, de novo sequencing, and more.
The combination of short inserts and longer reads increases the ability to fully characterize any genome.
