Accepting new optimization projects

Optimize Your Therapeutic Proteins Digitally

We design optimized protein and peptide variants using proprietary AI. You only test the best 30 to 96 candidates in your lab. Faster discovery, fewer experiments.

Three Steps to Better Proteins

A simple, efficient lab-in-the-loop process. You provide the protein, we deliver optimized variant designs ready for lab validation.

01

Submit Your Sequence

Provide us with your parental protein or peptide sequence and define the optimization goals: affinity, stability, immunogenicity, or multiple properties at once.

02

Proprietary AI Generates Variants

Our proprietary algorithm generates millions of candidates and selects the top 30-96 variants optimized for your target properties. Works from just a sequence alone.

03

Test in Your Lab

You test the designed variants in your lab. If the goal isn't reached, we run additional optimization rounds incorporating your experimental data for even better results.

AI-Driven Protein Engineering

Our proprietary algorithm combines protein large language models with evolutionary optimization to navigate the vast sequence space efficiently.

Protein-Type Agnostic

Works on any protein or peptide: antibodies, nanobodies, DARPins, peptides, and more. No structural constraints on input.

Property-Agnostic Optimization

Optimize any measurable property: binding affinity, aggregation, thermal stability, immunogenicity, selectivity, or multiple at once.

Integrates with Your Data

Combine with NGS from ribosome display, site saturation mutagenesis results, docking experiments, or your own property prediction models.

Minimal Starting Requirements

All we need is the parental amino acid sequence. Additional data helps but is not required to start optimizing.

Aggregation Eliminated in a Single Round

Size Exclusion Chromatography comparison of a parental protein and the best nuantic-optimized variant, from a project with Molecular Partners.

Aggregation completely removed with only 30 designed variants, while maintaining double-digit picomolar binding (~30 pM). Data shown with permission from Molecular Partners (blinded).

Optimization Highlights

Demonstrated across five pilot projects, covering a range of optimization objectives.

2'000x

Affinity Boost

400 nM to 150 pM when combining our algorithm with single point mutations from Site Saturation Mutagenesis. Our 30 designs outperformed 48 rational design variants.

20x

Single-Round Affinity Gain

400 nM to 14 nM in one optimization round with just 92 designed variants, no additional experimental input needed.

Gone

T-Cell Epitopes Removed

Eliminated predicted T-cell epitopes (NetMHCPan 4.1) while fully maintaining function and favorable biophysical properties.

Multi

Objective Optimization

Tackled multiple biophysical issues in parallel, producing an improved parental used on 2 out of 3 candidates in a lead panel for drug discovery.
