QIAGEN delivers the highest standard in contract DNA sequencing.
QIAGEN Sequencing Services — Single-Read Services Single-read sequencing services (96-well format) are ideal for small-scale analysis of cDNAs and ESTs, identification of clones, and verification of vector/insert transitions. All single read services include extensive documentation of the sequencing data, which is available via e-mail, FTP file, or on CD. Easy-read sequencing Easy-read sequencing is the service of choice for standard sequencing reactions. This highly automated service allows rapid processing of purified DNA samples. Easy-read sequencing is offered as tube service, or as a plate service for sequencing of samples in batches of 96. Easy-read sequencing does not include template purification (i.e., purification of PCR fragments or plasmid preparations prior to sequencing reaction setup). Sequencing reactions are set up using the DNA concentration information provided by the customer. All sequencing results are subjected to quality control using Phred20 algorithms (typically 600–900 bases of Phred20 controlled sequence are obtained). Quality documentation including raw data and quality clipped sequence data is delivered via e-mail, ftp, or on CD. Failed sequences are not repeated. This service provides high-quality single-stranded sequencing data 1–2 working days after receipt of purified DNA. Easy-sead sequencing provides: • Single sequencing reaction • Data collection to maximum read length • Typical read length up to 600–900 nt • Phred20 quality • >99% accuracy • Without template purification • Without incoming DNA quality check • No repeat reaction • Documentation of sequencing results Single-read sequencing If your sequencing reaction needs special attention we recommend our single-read sequencing Service. The sequencing results are manually checked and any failed sequencing reactions are repeated using modified sequencing parameters. This means that you get the most reliable service even from difficult samples (e.g., samples with high GC content). This service is offered with or without template purification as a plate service for sequencing of samples in batches of 96. Single-read sequencing with template preparation includes the purification of PCR fragments or plasmids prior the sequencing reaction setup. Templates are quality controlled to ensure an optimal sequencing reaction setup. All sequencing results are subjected to quality control using Phred20 algorithms (typically 600–900 bases of Phred20 controlled sequence are obtained). Quality documentation including raw data and quality clipped sequence data is delivered via e-mail, ftp, or on CD. Failed sequences are inspected by our experienced team and repeated using modified sequencing parameters. This service provides high-quality single-stranded sequencing data in 2–3 working days (3–4 working days with template purification). Single-read sequencing provides: • Single sequencing reaction • Incoming DNA quality check • Repeat reaction, if necessary • Data collection to maximum read length • Read length up to 600–900 nt • Phred20 quality • >99% accuracy • Documentation of sequencing results BAC end-sequencing End-sequencing of BACs, PACs, or cosmids. The results are manually checked by our experienced team and failed sequencing reactions are repeated using modified sequencing parameters. This means that you get the most reliable service even from difficult samples (e.g., samples with high GC content). This service is offered with or without template purification as a plate service for sequencing of samples in batches of 96. The delivery time is approximately 2–3 working days (3–4 working days with template purification). BAC End-Sequencing provides: • Single sequencing reaction • Incoming DNA quality check • Repeat reaction if necessary • Data collection to maximum read length • Read length up to 600–900 nt • Phred20 quality • >99% accuracy • Documentation of sequencing results siRNA hairpin run siRNA expression vector templates exhibit secondary structures that are often difficult to sequence.

Verification sequencing Under GLP-like conditions Verification sequencing Under GLP-like conditions provides confirmation of an already-known DNA sequence including comprehensive documentation of the sequencing results. Both DNA strands are completely sequenced to at least 4-fold coverage. The sequence is verified against a provided reference sequence. Documentation can be used for patent applications, litigations, or FDA submissions. GLP-like verification sequencing comprises:
QIAGEN Sequencing Services — De Novo Sequencing QIAGEN offers a number of de novo Sequencing services, providing accurate sequence data from unknown DNA. Sequencing quality ranges from single stranded primer walking for preliminary analysis to complete sequence analysis for patent submission. De novo publication-ready sequencing The de novo publication-ready sequencing service provides publication-ready DNA sequence from unknown template DNA. Both DNA strands are completely sequenced and the sequence is fully edited and assembled. Depending on the project size, different sequencing strategies can be applied (i.e., primer walking for plasmids or shotgun sequencing cosmids, BACs, or PACs). If you provide us with an E. coli host strain harbouring the construct of interest, we will apply the best strategy to determine the sequence and we will send back the sequencing results within 20 working days. De novo publication-ready sequencing provides:
De novo investigation-grade sequencing De novo investigation-grade sequencing provides a single stranded primer walking approach for preliminary analysis of unknown sequences. The target DNA is sequenced to single-strand coverage and the sequence is edited and assembled.

QIAGEN sequencing services has become a well-established participant in many publicly funded and private genome projects. The following table shows our contribution to selected projects:
One critical factor for successful genome sequencing is the generation of whole genome shotgun libraries. Our shotgun libraries are of an extremely high quality. Shotgun libraries with different insert sizes are used to establish the sequence either up to publication quality (>99.995% sequence accuracy) or up to a certain genomic coverage. We also offer various bioinformatic analyses including complete annotation and comparative sequencing. For large-scale projects, a dedicated project management plan and team is instigated to carry out all necessary work in due speed and to the highest accuracy and quality levels. QIAGEN Sequencing Services — Special Services QIAGEN offers a number of special services that complement our sequencing service. These services include the sequencing of templates with a high degree of secondary structure, the sequencing of genomic DNA, the detection of mutations, DNA purification, whole genome amplification, and bioinformatic analysis. siRNA hairpin run siRNA expression vector templates exhibit secondary structures that are often difficult to sequence. QIAGEN has developed a special sequencing reaction that enables accurate sequencing of siRNA expression vector templates.
