As a leading genomics company, CD Genomics provides next-generation sequencing and bioinformatics services to pharmaceutical and biotech companies, as well as academic and government agencies around the world, relying on advanced sequencing instruments and rich project experience. The next era of DNA sequencing technology, also known as termed long-read sequencing or third-generation sequencing (TGS), plays an increasingly important role in biology. We are offering long-read sequencing services from PacBio and Oxford Nanopore, giving researchers a wide range of cutting-edge sequencing services to suit particular needs at every stage of any projects. With years of experience in long-read sequencing technology, we are able to generate and analyze high quality data using the latest workflows.
Nanopore sequencing with Oxford Nanopore Technologies (ONT) systems is able to perform high-throughput long-read sequencing of both DNA and RNA samples, involving genomic DNA, amplified DNA, cDNA, and RNA. Briefly, the nanopore sequencer is based on a novel 'nanopore technology that uses nanopores embedded in an electro-resistant membrane. A voltage is set on the membrane to form an ionic current across the pores. When a DNA molecule tagged with tether proteinis guided and passes through a nanopore, the current variation, producing a characteristic signal, which is mainly influenced by four DNA bases. Then a base-calling algorithm converts the current variation back into the original DNA sequence in real-time.

ONT directly sequences the native strand of interest, without optics or amplification and its data has been proven improve de novo genome assemblies, structural genomic variant, and so on. ONT has been applied in genomic analysis, identification of pathogens, metagenomic environmental monitoring, food safety monitoring and other aspects of life sciences.
