How to install

  • Claude Science — enable the built-in SolubleMPNN research skill (Anthropic-hosted; not published to the public anthropics/life-sciences marketplace).
  • Run the model yourself — the upstream model is open source:
    git clone https://github.com/dauparas/LigandMPNN
    

    Follow the repo README for environment setup and model weights.

What it does

Runs ProteinMPNN with the SolubleMPNN weight set, which penalizes solvent-exposed hydrophobic residues to improve expression and solubility of designed proteins. Local inference only. The weights ship inside the ProteinMPNN / LigandMPNN repositories.

Primary use cases: Solubility-optimized protein design, improving expression of de novo designs

Notes

Claude Science: Featured as a research skill in Anthropic’s Claude Science. Its inclusion there is an independent signal of quality and trustworthiness for life-science work.

Local (your compute). A weight variant of ProteinMPNN; bundled in the ProteinMPNN / LigandMPNN repos.
