Vicuna

.

Nanobody design software.

Predict binding for nanobody–antigen pairs, and run virtual screens across natural repertoires or your own designs — to surface the binders worth making before they reach the bench.

Binding prediction Virtual screening Bench-in-the-loop
What it does

From a target to a ranked shortlist.

Vicuna brings binding prediction and virtual screening into one loop, so your team spends bench time only on nanobodies that have already earned it.

01

Binding prediction

Score nanobody–antigen pairs and rank candidates by predicted binding, before committing to synthesis.

02

Virtual screening

Screen large natural nanobody repertoires against your target in silico to find promising binders fast.

03

De novo design

Generate and optimize new nanobody designs, then score them through the same binding model.

04

Developability screening

Flag aggregation, solubility, and stability liabilities early — the failures that usually surface late.

Developability, up front

See the liabilities before you make the molecule.

Every candidate gets a profile across the properties that decide whether a binder survives manufacturing and the clinic — consistent, comparable, and ready to triage.

Profiled properties
  • Binding affinity
  • Specificity
  • Thermal stability
  • Aggregation risk
  • Solubility

Most nanobody programs don't fail at the idea. They fail at developability — late, and expensively.

Why we built Vicuna
The loop

Design, in a tight cycle.

Vicuna is built to run with your lab, not instead of it — each round of bench data sharpens the next round of design.

Assemble

Start from natural nanobody repertoires or your own de novo designs.

Predict

Score nanobody–antigen binding and developability in silico.

Screen

Rank, triage, and select the shortlist worth synthesizing.

Refine

Feed bench results back in to sharpen the next round.
