Sanger Sequencing

Get the “gold standard” of sequencing from a US-based lab with 18 years of genomics experience. Formerly Macrogen USA, Psomagen offers quick turnaround times, quality results, and decades of industry experience. Our staff is well-trained and ready to help with your next sequencing project.

What Is Sanger Sequencing?

Sanger Sequencing—also known as capillary electrophoresis sequencing (CES)—is the oldest proven process of sequencing regions of DNA by using oligonucleotide primers and chain termination.

It is commonly selected to sequence polymerase chain reaction (PCR) products, plasmid DNA, and bacterial artificial chromosomes (BACs).

Why Is Studying Sanger Sequencing Important?

The original sequencing method preceding next-generation sequencing (NGS), Sanger sequencing is useful as a low-cost, high accuracy method for interrogating small DNA regions in a limited number of samples.

Technologies Used for Sanger Sequencing

Plasmid and PCR Product Sequencing

  • Detect the presence or absence of a target sequence in PCR products
  • Use PCR prior to Sanger sequencing to create multiple copies of the sequence, making it easier to generate tagged fragments
  • Determine identity and order of sequence by using primers targeting the plasmid backbone or insert sequence
  • Available for Psomagen's EZ-Seq pre-order service

Difficult Region Sequencing

  • Sequence DNA regions that have been historically difficult to sequence
  • Understand areas with high GC or GT, unusual secondary structure, repetitive sequence, pseudogenes, siRNA with hairpin structure, and homopolymeric tracts (PolyA, PolyG)

Microbial Identification

  • Amplify and sequence bacterial, viral, and fungal samples
  • Identify antibiotic resistance and virulence in pathogenic samples
  • Sequence 16S, 18S, and 28S ribosomal RNA (rRNA), as well as ITS regions

Primer Walking

  • Verify template sequences where little information is known using client-provided primers or Psomagen’s primer design service
  • Close gaps between unlinked contigs and increase read length by 800 bps per walk

Genotyping

  • Sequence DNA within sections of the genome, particularly those that contribute to phenotype
  • Identify SNPs and analyze relevant genomic regions

Rolling Circle Amplification (Direct Colony Sequencing)

  • Directly sequence bacterial or fungal colony samples
  • Amplify very small amounts of double- or single-stranded DNA templates
  • Eliminate the need for plasmid preparation

We've Got the Right Option For You!

Whether you're looking to send premixed samples, choose a standard primer, or create your own project, we can help.

Standard Sequencing

Standard Sanger sequencing service is the perfect choice for PCR products, plasmids, and BACs. Our state-of-the-art robotics and instrumentation deliver fast turnaround times, quality results, and competitive pricing.

WIth over 100 locations on the east coast, samples are promptly received at one of our US-based laboratories. High quality data can be downloaded via our secure client portal.

EZ-Seq (barcoding)

Save time with our EZ-Seq service. Purchase pre-printed barcodes, mix your sample and primer before submission, and get results fast.

Skip the data input process of an order form. Data is reported out by tube/plate barcode and position.

Custom Sequencing

Customizing your sequencing services gives you the freedom to select primer sets and additional sequencing technologies, like primer design and synthesis, NGS validations, and fragment analysis.

Earn Free Sanger Sequencing Reactions!

We have special deals for new customers, and ways to earn when your colleagues order (hooray to FREE reactions)!

Quotes From Our Clients

I've been using their sequencing services for ten years - still going back! Shipment is fast, instructions for preparing sample plates are clear, handling by technicians and communication by Psomagen is well-done.

Director

Botanical Research Institute

I chose Psomagen because of the price and US-based labs. We've used Psomagen before and were very satisfied. The people were responsive and helpful and the work done was very good.

Professor

University Research Laboratory

I have used Psomagen for sequencing my clones for a site-directed mutagenesis screen. I enjoy the speed of delivery and the fact that I get my results before I wake up the next day. Customer care is present to answer all questions and is quick to resolve issues. I believe this is value for the money.

Biomedical Scientist

Rutgers University

I've been sending Sanger-sequencing and whole-plasmid-sequencing samples to Psomagen for a decade. I love and appreciate their service. They have great technicians who gladly re-queue my samples if there's an error. The best part is the quick turn-around-time. On Monday they picked up two of my plasmids from a dropbox. Four hours later, I had results. I don't know how they do it, but I'm grateful. Thank you.
