Growth
From DNA to data, Twist provides solutions for every stage of the biological continuum.
“We’re consolidating these tools in one secure application, powered by advanced AI capabilities, that
doesn’t require researchers to manage complex infrastructure or write code, and they can also easily
find and work with Twist Bioscience.”
“Twist has been the leading CRO that has reproduced results in a consistent manner. Our models are
very sensitive, and we are very happy with Twist’s data quality.”
“Out of all the solutions we have tried, Twist’s oligos are the most faithful to our designs. We
absolutely need this fidelity when we’re validating AI outputs.”
“Outsourcing cloning to Twist is on track to save us ~2.6 years worth of FTE time in 2026 alone.”
“We rely on high accuracy and a low error rate during the synthesis process… We have an equal
distribution of nearly all of the variance inside the library; 95% to 99% of what we sequence matches
what we were expecting.”

Assay suite
Built for IND. Run at AI speed.
Run the assays you need to reach IND, delivered as structured, AI-ready data.
Determine top candidates by confirming, ranking, and binning your binders. Example dataset shown for each
assay.
Confirm Binding by Flow Cytometry
Confirm target engagement on cells expressing native antigen. Generates dose-response binding curves
for ranking.
Single-Point Kinetics by BLI
Rapidly confirm binding across large antibody panels at one concentration for early hit triage,
before committing to full kinetic analysis.
KD Affinity Determination by BLI
Determine full kinetics and affinity across a concentration series. Provides orthogonal confirmation
to SPR.
KD Affinity Determination by SPR
Determine full binding kinetics (ka, kd, KD) for large antibody panels using high-throughput surface
plasmon resonance.
Epitope Binning by SPR
Map competitive binding relationships across large antibody panels to identify epitope families and
guide lead selection.
Epitope Binning by BLI
Map competitive binding to identify epitope diversity and guide lead selection. Ideal for smaller
panels.
Flag aggregation, stability, and polyspecificity risk early, benchmarked to clinical reference antibodies.
Selected assays and datasets are shown below.
Analytical SEC (aSEC)
Quantify monomeric purity and detect aggregates or degradation products.
Thermostability (nanoDSF)
Measure structural integrity under thermal stress, with three parameters per sample.
Polyspecificity Screen (Baculovirus Particle (BVP) ELISA)
Screen for non-specific binding, which correlates with faster serum clearance in vivo.
Self-Interaction Test (Affinity Capture-Self Interaction Nanoparticle Spectroscopy (AC-SINS))
Detect self-interaction propensity, an early predictor of aggregation and clearance risk.
Hydrophobic Interaction Screen (Hydrophobic Interaction, HI)
Rank candidates by surface hydrophobicity, a key driver of aggregation and non-specific binding.
Non-specific Binding Check (Ovalbumin Off-Target)
Screen for off-target binding to ovalbumin, a confirmatory measure of polyspecificity.
Size Distribution (DLS)
Assess particle size homogeneity and flag candidates with high polydispersity as early aggregation
liabilities.
Test function on cells, with custom assays for bespoke needs. Example dataset shown for each assay.
Signaling Assays (Off-the-Shelf)
Quantify agonist or antagonist activity through defined signaling pathways.
Internalization
Quantify receptor internalization extent following antibody engagement.
Custom Assay Development
For programs requiring non-standard cell types, proprietary cell lines, or bespoke readouts not
covered by off-the-shelf panels.
