The Challenge

From silicon to cell:
the validation bottleneck

Your AI generates millions of candidates. The traditional wet-lab infrastructure can only test hundreds. The bottleneck is no longer computation — it's trustworthy validation data at scale.

Where existing High-Throughput platforms fall short

Single-condition constraints

Fixed, single-condition pipelines aren't optimal for every protein. A design that fails in one environment may express perfectly in another — rigid systems never find out.

Missing context on failures

Pass/fail reports leave R&D teams without the diagnostic insights needed to understand why a design didn't express. No context means no path forward.

Data fidelity risks

Expression artifacts recorded as biological failures inject false negatives into your training data — quietly degrading model quality with every iteration.

Who We Work With

Built for every protein
engineering workflow

We validate the proteins your pipeline produces — across expression environments, target classes, and research goals.

De Novo Binders & Miniproteins

Expression, affinity, and thermostability profiling for AI-designed miniproteins, constrained binders, and computationally scaffolded candidates — RFdiffusion, BindCraft outputs. Epitope binning available on request.

Nanobody & Single-Domain Antibody Validation

VHHs and sdAbs from library selections, humanization campaigns, or computational design — expression profiling, BLI affinity, and Tm in a single submission without cell-based expression limitations.

Variant Libraries & Mutant Panels

High-throughput Tm profiling and expression yield across point mutation libraries and deep mutational scans — clean, ML-ready data for model retraining.

De Novo Scaffolds & Structural Designs

Multi-environment rescue and thermostability profiling for computationally designed scaffolds with no natural homologs — where expression is hardest to predict and fallback is most valuable.

Enzyme Engineering & Biocatalysis

Expression and solubility profiling across variant libraries. Clean data distinguishing true catalytic failures from expression artifacts — essential for directed evolution pipelines.

Complex Biologics & Therapeutic Proteins

Cytokines, growth factors, and disulfide-rich proteins validated with our redox-tuned rescue environment. Thermostability data directly relevant to formulation and stability screening.

Membrane Proteins

Nanodisc-integrated cell-free expression for targets that fail conventional systems. Our fallback matrix includes dedicated membrane and cofactor environments built for exactly these difficult classes.

Vaccines & Immunogens

Expression and conformational integrity profiling for antigen candidates — validating that designs fold as intended before committing to downstream immunology work.

Non-Canonical & Modified Proteins

Cell-free systems are particularly powerful for proteins carrying non-natural amino acids, site-specific modifications, or PTMs — modifications can be introduced directly into the reaction, enabling expression that cell-based systems cannot easily support.

Core pipeline: expression profiling, BLI affinity, and thermostability. Functional assays for specific targets are available on request and scoped separately.

The Platform

The validation engine for
modern protein engineering

High-throughput automation paired with expert scientists — delivering the clean, high-fidelity data your AI models and R&D pipelines actually need.

01 — Throughput

Scalable high-throughput pipelines

Every run processed in 384-well format — high-throughput plate density with scientist-executed precision at every step.

02 — Resilience

The built-in fallback matrix

Proteins that fail the standard mix are automatically rerouted through specialized microenvironments to rescue expression — at no extra cost.

03 — Execution

Scientist-led execution

Expert scientists manage every run — flagging anomalies, maintaining standardization, and ensuring every data point is reproducible and trustworthy.

04 — Output

Targeted core characterization

Expression profiling, BLI affinity screening, and thermostability — the metrics that matter most, in a single unified report.

Step 1

Submit sequence

Your design enters our system and is queued for the PURE cell-free baseline run.

Step 2

Standard expression

Run in our PURE cell-free baseline — fastest turnaround. Most proteins express here.

Step 3

Scientist validation

Every data point reviewed by our scientists — anomalies caught before the experiments are concluded.

Output

Full report delivered

Rich, continuous metrics with diagnostic context — not a binary pass/fail.

If expression fails
Automated Fallback Matrix Included at no extra cost · triggered automatically
When a sequence fails in the baseline environment, our system evaluates all available rescue environments simultaneously and selects the best-matched one for the first retry — then a different environment for the second, and a third if needed. Rescue runs are included at no extra cost and may extend overall turnaround time.
Available rescue environments — selected by target sequence properties
Chaperone, Redox & Buffer

Condition-Specific

Target-tailored microenvironment variation — selected based on sequence properties and prior failure mode

Every run
Failures come with answers, not just numbers. Each report explains what failed, which rescue environment responded, and what it means for your next design iteration.
ML-ready output No false negatives
Why Valyn Biosciences

The architecture of better data

We are not just building a faster lab. We are building a smarter one.

Dynamic multi-environment routing

Valyn Biosciences is architected from the ground up as a dynamic, multi-environment platform. Challenging designs are automatically rerouted through alternative cell-free conditions — rescue runs are included in every base submission.

Human-in-the-loop thechallenge solving

Every plate is run and reviewed directly by our scientists — not delegated to automation. Hands-on execution means complete accountability for every data point, and direct troubleshooting when things don't behave as expected.

High-fidelity, ML-ready data

Rich, continuous metrics — yield, affinity, and thermostability across expression environments. Not a binary pass/fail, but precise inputs for your model's next iteration.
