Plasmids and PCR products are the bread and butter of molecular biology labs all over the world.

Broad-based access to cost-effective, next-generation sequencing (NGS) and advances in synthetic biology have revolutionized the scale to which plasmids can be constructed, screened, and manipulated for wide-ranging applications, including biomarker discovery, antibody engineering, genome editing, and gene therapy. However, NGS library preparation throughput, performance, and cost, remain bottlenecks in high-throughput plasmid sequencing.

Amplicon sequencing is a targeted NGS approach that enables researchers to analyze genetic variants in specific regions of a genome. This technique is particularly useful for detection of hot-spot mutations, copy number variations, gene fusions, insertions, deletions and single nucleotide polymorphisms (SNPs). Because of the sensibility and the versatility of amplicon sequencing, efficient library preparation is a must.

Our library preparation kits offer robust workflow solutions for amplicon sequencing by focusing on scalability (high-throughput multiplexing), speed (as fast as 90 minutes with some kits), and cost-effectiveness. Our workflows are easy to implement and automation-friendly. We provide improved yield across a broad range of sample types in various disciplines, including precision medicine, gene therapy, and gene editing.

Whether it’s your first library prep or your hundredth, seqWell scientists are dedicated to helping you achieve high-quality multiplexed plasmid or amplicon libraries with quality sequencing data allowing you to characterize your targeted gene or verify your plasmid backbone. Our products are backed by intensive research and development. Our knowledgeable and highly skilled application and support team is available to provide assistance and answer questions at every step of your project.

RECORDED WEBINAR

In this presentation, Georgia Giannoukos, Ph.D., Director of Next Generation Sequencing at Editas Medicine, highlights how her organization has leveraged Tagify™ – seqWell’s adapter-loaded Tn5 transposase reagent, for their UDiTaS process to assess CRISPR on-target editing and structural changes. If reading is your preference, a transcription of this webinar can be found here.

Our transposase-based technology removes critical bottlenecks in NGS workflows by enabling scientists to prepare samples into libraries and get them onto sequencers quickly and with higher performance.

Current technology is limited by the number of samples sequenced simultaneously (multiplexing), sensitivity, and turnaround time. seqWell’s technology combines a simple and efficient workflow with high sensitivity and unparalleled scalability that is ideal for applications such as high-throughput plasmid and amplicon sequencing, and for use in gene therapy and sythetic biology.

Read distributions by plate and well position for 960 plasmids sequencing in a single Illumina® MiSeq™ (2 x 250 bp) run. Samples were processed in 10 plates of 96 plasmids each with the plexWell 384 Library Preparation Kit. Assemblies were obtained for 955 of the 960 plasmids (99.5%), and were free of ambiguities for 99.2% of the samples.

Our cost-effective NGS workflow solutions can provide 30 – 50% savings compared to other methods and reduce processing time from sample to result.

A crucial technology that we use to build almost all of our products is an enzyme called Tn5 transposase, which is an incredibly versatile tool for scaling and simplifying NGS workflows. We have found Tn5 to be an incredibly powerful platform for creating library chemistry with several unique advantages, such as auto-normalization and multiplexing with purpose-built reagents. These reagents form the core capabilities that our products are based on. 

The following products support specific applications like plasmid and amplicon sequencing, synthetic construct sequencing, microbial genomics, and metagomics/microbiome screening, in both research and commercial settings.

ExpressPlex™ 2.0 Library Prep Kit

This kit was designed for applications that focus on speed and volume versus high-depth reads. For example, if your lab is transitioning away from Sanger because you need to process at larger volumes, ExpressPlex 2.0 can dramatically shorten time to data.   ExpressPlex 2.0 is one-step tagmentation-based library preparation method that is automation-friendly and extremely scalable.
