Unrivaled speed
Submit a design and your panel ships within a day, accelerating your MRD research workflow.
MRD Express: Sensitive.
Tumor-specific. Fast.
Get hybrid capture panels produced at scale, shipped within a day
after you submit a design.* Never trade sensitivity for turnaround again.
Tumor-informed MRD sequencing panels, built within a day*
MRD Express lets you design a hybrid capture panel around variants in tumor sequencing data, shipping within a day of design submission. Track ctDNA at the depth molecular residual disease research requires, scaled to your workflow volume, with the speed key decisions demand.
Panel synthesis to panel shipped
within 1 day*
Detection above background
Probes per panel
Submit a design and your panel ships within a day, accelerating your MRD research workflow.
Upload a BED or FASTA file to design and order in minutes. Have full control over your design.
Capture thousands of tumor-specific variants to detect the faint ctDNA signals typical with MRD research.
For workflows running at scale, Twist APIs turn sequencing data into a placed order with no manual steps.
Is your workflow enterprise-scale?
Automate production of thousands of tumor-informed panels per day, with touchless ordering and manufactured to ISO 13485 standards.
Traditional barriers with other approaches
5+ days with legacy hybrid capture workflows
Narrow with amplicon-based panels (16-64 targets)
Not possible with off-the-shelf or fixed panels
Process bottlenecks increase as order volume increases
MRD Express
Within a day from order to hybrid capture panel shipment
Up to 10,000 tumor-informed probes per panel
MRD panels are configured to exact target set
API integrates directly with LIMS for high volume workflow
Tumor-informed MRD research just got easier
Don't outsource your MRD research. Incorporating MRD Express complements your in-house infrastructure, giving you exceptional control over your workflow, timelines, and costs.

What’s still holding MRD back?
A roundtable with BloodPAC, Stanford, and Twist on what still limits tumor-informed MRD: standardized limit-of-detection definitions, comparing assays across studies, and getting tumor-informed panels back in days, not weeks.

Targets per tumor-informed panel
See how IntegraGen built a tumor-informed MRD workflow on Twist panels, pairing whole-exome sequencing of tumor tissue with target enrichment of plasma, then validated it retrospectively at a 0.003% limit of detection.

One ISO-grade quality standard across every panel, verified lot by lot.
Scale the design without sacrificing coverage.
Hard-to-capture low-GC variants stay measurable instead of dropping out.
Built for calling variants at the fractions MRD research actually encounters.

Ready to get started?
Start your design now or speak with an expert to scope your project.
Drag and drop BED, FASTA, CSV, TSV or TXT files. Each file becomes its own panel design.
Choose your reference genome and tiling density, protect key regions, or edit many panels at once.
Follow live design status, see probe counts and prices, and download BED files that flag coverage gaps.
Resubmit with your uncovered-bases file as protected regions to cover them, at a higher off-target rate.
Match your reference genome, then load the covered and uncovered BED files side by side to judge any gaps.
Check probe counts, reactions and price per panel, add shipping details, then submit or save for later.

MRD Express orders ship on dry ice as soon as they’re ready. For international orders, our standard ship days are chosen to avoid weekend delays in customs or at closed receiving sites:
Orders ready on Tuesday or Wednesday ship the same day if the carrier expects delivery before the weekend. To avoid any chance of weekend arrival, ask us to hold your order until the next scheduled ship day.
