Traditional Barriers with Other Panels
traditional biopsies
Twist Solutions
Uneven coverage and GC bias leading to missed variants or dropouts Precision probe synthesis ensures balanced coverage across GC-rich and complex regions, leading to fewer dropouts
Probe redundancy and off-target capture wasting reads and budget Exon-aware, junction-spanning design captures isoforms, fusions, and hard-to-reach exons
Complex splicing and isoform diversity missed by rigid, pre-designed panels Uniform, reproducible data reduces revalidation cycles and speeds time to confident results

Smarter Designs, Better Data

METHYLATION

Capture methylation data with a custom DNA methylation panel. Twist’s novel design approach achieves high uniformity and retains the methylation pattern by printing four different probe species for each target: fully methylated, fully unmethylated, sense, and antisense probes.

Highlighted applications

Cancer Research

In applications like liquid biopsy minimal residual disease (MRD) testing, off-the-shelf panels often fall short. This example from IntegraGen shows how Twist Custom NGS Panels enabled high sensitivity and scalability for liquid biopsy–based cancer monitoring.

What Scientists Have to Say

Twist sales may make absurd claims about how good Twist Custom Panels are, but we have found no reason to dispute those claims. We didn’t believe it until we ran their panel ourselves. Our last run had an average uniformity of 99.5%, meaning that you can drop your average coverage right down. We’ve basically doubled the number of samples we can fit on a run.

MARK DAVIS, Ph.D.

Scientist, Neurogenetics Unit, Department of Diagnostic Genomics PathWest Laboratory Medicine, Australia

Other companies were cutting costs and focusing more on fitting everything into one box rather than working with customers to devise custom probes that fit their highly specific research needs. Twist bucked the trend.”

LYDIA SMITH

Evolutionary Genetics Lab Manager, UC Berkeley

Twist’s Custom Panels allowed us to focus on important, medically relevant genes instead of forcing us to work with a whole genome. The panel was concise, with a simple protocol and cost was reasonable with very good candidate variants already curated by the literature.”

FAQ

The standard probe length for a custom panel is 120 bp; however, we do offer custom probe lengths (80, 100, 120 bp, for example). All of the probes in a panel must be the same length.

Yes, in addition to designing panels for fusions and SNPs, Twist can also design panels for viruses, MSIs (microsatellite instabilities), structural variants, copy number variants (CNVs), and InDels (insertion/deletions).

Yes, Twist can design a custom panel for Targeted Methylation Sequencing. An application note can be found here.

Yes, Twist probes are double stranded DNA.

Twist performed a NGS quality control by sequencing the probes to ensure representation in the pool.
