DNA Library Sequencing Services

THE FOUNDATION OF ALL NGS LIBRARY PREPARATION

DNA is the instruction set for life, the molecule that directs how an organism develops, functions, and responds to its environment. Sequencing is how researchers read that instruction set, and it is what makes it possible to pinpoint the genetic causes of disease, uncover new therapeutic targets and advance more personalized approaches to medicine. Before any of that can happen, a sample has to go through library preparation: converting raw DNA into a “sequencing library,” fragmented, tagged molecules that a sequencing instrument can actually read.

The choice of library preparation depends on sample type and sequencing technology. Short-read sequencing platforms, such as Illumina, provide highly accurate data for applications including whole genome, exome, and targeted sequencing. Long read technologies, including PacBio and Oxford Nanopore, enable sequencing of much larger DNA fragments, making them ideal for resolving structural variants, repetitive regions, haplotype phasing, and de novo genome assembly. By selecting the appropriate library preparation strategy and sequencing platform, researchers can generate high-quality data tailored to their specific scientific and clinical objectives.

Your Project Details

WGS determines the complete DNA sequence of an organism, coding and non-coding regions alike, enabling discovery of genetic variation, structural changes, and novel genomic features that targeted methods would miss entirely..

WGS is the strongest option when the research question is not yet narrowed to specific genes or regions: population genetics studies, new reference genome generation, structural variant discovery, or any project where comprehensive genomic coverage matters more than sequencing depth at any single locus.

Chromosome conformation capture, commonly known as Hi-C, measures which regions of DNA are in physical proximity to each other inside the cell, capturing the three-dimensional organization of the genome. This contact data is used to order and orient sequence fragments into chromosome length scaffolds, substantially improving genome assembly quality. SeqMatic offers Hi-C library preparation through Dovetail Genomics and Phase Genomics kits.

This is the strongest option for scaffolding a new genome assembly into chromosome length sequences, resolving repetitive regions that short read or long read sequencing alone cannot correctly order, or studying three-dimensional genome architecture and chromatin interactions directly.

WES focuses sequencing on the protein coding regions of the genome, roughly 1 to 2% of total DNA, but the region responsible for the majority of known disease associated variants.

WES is the strongest option when the research question centers on coding region variants: clinical variant discovery, rare disease research, or projects where whole genome depth is not necessary to answer the question.

Amplicon sequencing targets specific genomic regions or engineered constructs directly, rather than sequencing an entire genome or exome.

This is the strongest option for validating genetic modification of any project where the region of interest is already known and genome wide coverage would be unnecessary overhead.

Metagenomic sequencing provides a comprehensive view of microbial communities directly from environmental, clinical, or biological samples without the need to isolate or culture individual organisms. SeqMatic offers shotgun metagenomic as well as 16S, 18S, and ITS sequencing to support microbial community profiling and taxonomic analysis. Shotgun sequencing captures DNA from the broad range of microorganisms present in a sample, including bacteria, fungi, and viruses, providing the most comprehensive view of community composition and functional potential. In contrast, 16S, 18S, and ITS sequencing focus on specific genetic markers to identify and characterize bacterial, eukaryotic, and fungal communities, respectively, enabling targeted taxonomic classification and phylogenetic analysis.

Metagenomics is the strongest option for microbial identification, community composition studies, and any project where the organisms present are not known in advance or cannot be cultured using traditional methods. It also supports de novo characterization of novel or emerging organisms directly from complex samples, and comparison of community composition across many samples at once.

Standard sequencing workflows and reference genomes are built around a handful of commonly studied model organisms. Non-model organism sequencing extends the same NGS methods to species without existing references: agricultural crops, livestock, wildlife, and other understudied lifeforms.

This is used for biodiversity research, agricultural breeding programs or evolutionary studies where no existing reference genome is available and custom bioinformatics is often required.

Viral genome sequencing determines the genetic sequence of viruses directly from clinical, environmental, or laboratory samples, supporting analysis of mutation patterns, strain relationships, and evolution over time.

This is used for outbreak tracking, viral strain identification, and studies of viral evolution, where mutation level resolution is needed and no single reference sequence fully captures the population being studied.

Quality Control You Can See

Quality control at SeqMatic begins immediately after extraction. SeqMatic qualifies each DNA sample before library preparation and shares the results with the customer for review and approval. If a sample does not meet the requirements, the team consults with the customer on how best to proceed. During library preparation, libraries are evaluated using TapeStation for fragment size and integrity assessment, then normalized and pooled based on molar concentration to ensure consistent sequencing performance. A MiSeq test run is then used to validate pool performance and analyzed at the sample level to assess library representation. SeqMatic also utilizes its proprietary TailorMix (Denatured) Dual Indexed PhiX control Library or TailorMix (Non-Denatured) Dual Indexed PhiX control Library to reduce index crosstalk and improve sequencing accuracy.

Frequently Asked Questions

How do I choose between WGS, WES, amplicon sequencing, and metagenomics?

Choose WGS if you need comprehensive genomic coverage or do not yet know which regions matter: population genetics, new genome assembly, or structural variant discovery. Choose WES if your research question centers on protein coding, disease associated variants and you want to reduce cost and turnaround versus full genome coverage. Choose amplicon sequencing if you already know the exact region or construct you need validated. Choose metagenomics if you are characterizing a microbial community rather than a single organism. SeqMatic’s team helps confirm the right method during project consultation.

How much sequencing depth do I need for my project?

Recommended coverage depends on the application. General starting points: germline variant detection typically uses 30 to 50x coverage, somatic or tumor versus normal comparisons often require 60x to 100x or higher, population studies typically use 20 to 50x, and de novo genome assembly typically requires 100x or more on short read platforms, or 50 to 100x on long read platforms. SeqMatic’s team helps determine the right depth for your specific research question during project consultation. For detailed specifications, see the table under “Recommended Sequencing depth”.

Does SeqMatic provide bioinformatics analysis for single cell data?

Yes, SeqMatic provides custom bioinformatics at three tiers — Primary (alignment and quantification), Secondary (QC, normalization, and differential expression), and Tertiary (pathway, gene ontology, and functional interpretation) and can go deeper per customer request, including support for non-model organisms.

Bioinformatics services → 

How does SeqMatic ensure data quality?

SeqMatic’s quality control process is designed to catch problems before they affect a full sequencing run. Samples are evaluated at an interim QC checkpoint after extraction, and again with a MiSeq test run to validate pool performance before committing to a full run, so issues are identified and addressed early rather than discovered after sequencing is complete.

What is the turnaround for DNA Sequencing?

Standard DNA sequencing projects at SeqMatic are completed in 3 to 6 weeks from sample receipt to data delivery. This includes sample QC, library preparation, sequencing, and primary data analysis. Expedited turnaround is available in as few as 2 weeks for time sensitive projects. Actual turnaround depends on sample quality, target cell number, sequencing depth, and the scope of bioinformatics analysis requested.

Is SeqMatic CLIA and CAP certified?

Yes. CLIA/CAP accredited. All DNA projects are processed under CLIA quality standards that maintain consistency and reproducibility across NGS workflows.

How much does DNA sequencing cost?

The cost of a DNA sequencing project depends on several factors, and SeqMatic provides customized quotes based on each study’s requirements. The primary variables that affect pricing are the sequencing method (WGS, WES, amplicon, or metagenomics), sample number and input quality, sequencing depth, platform selection, and the scope of bioinformatics requested. SeqMatic’s scientists work with customers during project consultation to design an experiment that balances scientific goals with budget.
