ExpressPlex™ 2.0 Library Prep Kit – Early Access
ExpressPlex 2.0 Early Access: The workflow simplicity of one-step library prep combined with the performance of TnX for high throughput sequencing of plasmids, amplicons and other synthetic constructs.
- Improved performance: TnX transposase for reduced bias and improved coverage uniformity
- Ease of use: Fragmentation, barcoding, and amplification in a single step
- Rapid: 100-minute workflow (30 minutes or less hands-on) with pre-plated, reaction-ready reagents
- Scalable: High-level sample multiplexing and auto normalization
We’ve unleashed TnX, our next generation transposase, in ExpressPlex 2.0 – a library prep kit that changes your NGS synthetic construct sequencing workflow forever!
ExpressPlex 2.0 is an automation-friendly, one-step library prep powered by TnX to reduce bias and improve coverage uniformity using a highly streamlined workflow for sequencing plasmids, amplicons and other synthetic constructs.
ExpressPlex 2.0 One-step Library Prep
“Anyone can rapidly produce a quality NGS library using ExpressPlex 2.0!”
– Zachary Neuschaefer, Principal NGS Engineer, LifeMine Therapeutics
TnX Transposase: Quality Libraries for Quality Sequencing
ExpressPlex 2.0 uses tagmentation powered by TnX, the next generation transposase, to simultaneously fragment & index sample DNA. Average fragment size ranges from 400-1200 bp.

TnX: Transposase Engineered for Reduced Insertion Bias
Better transposase = better sequencing. Take your plasmid and amplicon screening to the next level!
ExpressPlex 2.0 is the only library prep kit powered by TnX! TnX was engineered to reduce insertional bias to improve uniformity of coverage. When directly compared to a Tn5-based competitor library prep kit for sequencing of 2 different plasmids, ExpressPlex 2.0 produced significantly lower CVs and range of coverage (max/min).
Library preparation for pUC19 and pMal-c67 was conducted using ExpressPlex 2.0 kit and a Tn5-based competitor kit using standard manufacturers’ protocols. Libraries were sequenced using an Illumina MiSeq.
initial ExpressPlex 2.0 users said it exceeded their workflow, productivity & cost expectations!
Recorded Webinar | Octant Bio
The game-changing capabilities enabled by the ExpressPlex workflow were highlighted in a webinar collaboration with the synthetic biology team from Octant Bio, a drug discovery company located in Emeryville, CA. Octant’s Henry Chan, PhD (Synthetic Biology Lead) and Bryan Jiang (Research Associate) discussed the application of ExpressPlex to OCTOPUS, the high-throughput plasmid sequencing platform that powers Octant’s therapeutic discovery platform. Watch the video to discover how ExpressPlex has dramatically improved OCTOPUS and accelerated their overall discovery process.
Improving Sustainability Through Streamlined Protocols
The automation-friendly ExpressPlex one-step tagmentation workflow enables a >80% reduction in tips/plastics usage. We help drive sustainability not only in our internal sequencing services pipeline, but for our customers across the globe.
