ImmuneFold Antibody

ImmuneFold predicts atomic-level 3D structures of antibodies and nanobodies from amino acid sequences using a LoRA-fine-tuned ESMFold model specialized for immune proteins. The API supports heavy/light chain or single-domain inputs (up to 256 residues per chain) and optional antigen context via a PDB snippet, returning PDB coordinates with pLDDT and pTM confidence scores. ImmuneFold focuses on accurate modeling of CDRs, particularly CDR H3, for structure-guided antibody engineering and immunotherapy design workflows.
