seqWell vs. Illumina (Nextera XT)
| seqWell (LongPlex / ExpressPlex) | Illumina (Nextera XT) | |
| Workflow Speed | 100-155 minutes (consolidated worksteps) | Longer, multi-step processes |
| Normalization | Auto-normalized workflows | Requires precise manual input quantification |
| GC Bias | Significantly reduced for better uniformity | Higher variability across samples, inconsistencies |
| Cost Efficiency | Lower plastics usage, fewer repeat steps | Higher consumable and labor costs |
| Scalability | Up to 384 samples per run | Limited to smaller batch sizes |
TnX Transposase: New Next-Level Enzyme
Workflow Simplicity & Performance powered by TnX Transposase
seqWell’s TnX enzyme is a game-changer addressing the limitations of traditional Tn5-based workflows. The enhanced performance of seqWell’s enzymes translates to:
Reduced Bias, Better Data Quality: Improved GC and insertion-site profiles for more uniform sequencing reads with minimal variability and coverage with fewer gaps.
Enhanced Activity, Higher Efficiency: Higher specific activity ensures better library yield and conversion efficiency for faster, more reliable library preparation with fewer worksteps.
Unparalleled robustness and flexibility: Reliably performing in stringent buffers. For applications from microbial sequencing to complex whole-genome analysis.
| TnX Enzyme | Traditional Tn5 Enzyme | |
| Insertion Bias | Significantly reduced, more randomized insertion | Moderate |
| GC Coverage | Improved uniformity, Fewer gaps in regions of interest | Good |
| Specific Activity | Increased specific activity increased library yields | Standard |
| Library Complexity | Enhanced for diverse reads, convert more DNA into library | Moderate |
| Reaction Conditions | Robust across conditions, ability to formulate in stringent buffers | Standard |
Combining sequence analysis, multi-parameter performance data, and machine learning for truly directed evolution.
Key Products
Now Available!
PhiRx™ Indexed Control
PhiRx™ Indexed Control is now available as an easy, drop-in spike-in control to maximize the performance of XLEAP-SBS chemistry on high-throughput Illumina platforms. By color-balancing both sequencing reads and barcodes, PhiRx improves signal uniformity, boosts data quality, and helps recover reads that would otherwise be lost as “undetermined.”
+ Optimizes index diversity for XLEAP sequencing
+ Seamless spike-in alternative to Illumina PhiX Control v3
+ Corrects color balance issues in low-diversity and small batch runs
PhiRx provides diversity in both index and insert reads and is supplied at the same size and price point as Illumina’s PhiX controls, making adoption straightforward for existing workflows.
