3dpredict/Ab is a Software-as-a-Service (SaaS) platform that streamlines decision-making in antibody discovery by allowing rapid antibody developability assessment.
Its ensemble-based predictions help overcome the single-structure bias, supporting quick candidate selection and progression through the discovery pipeline.
The platform allows antibody modelers and engineers to identify potential liabilities and compare antibody variants based on physics-based property calculations.
Its scalable cloud architecture supports high-throughput screening and can be integrated with existing discovery workflows for efficient data management and analysis.
Successfully prioritize antibodies to accelerate your lead optimization phase
Ensemble-based predictions at your fingertips
Accurate antibody developability insights from ensemble-based protein property calculations accounting for pH-dependence and flexibility
User-friendly platform built for efficient discoveries
Intuitive web-based interface designed for both small and big antibody discovery groups in pharma and biotech
Instant access to focus on science, not IT hassle
Immediately accessible through a highly reliable and secure cloud environment (ISO 27001) without any deployment efforts
Streamline your antibody discovery workflows with accurate ensemble-based predictions
Sequence/structure upload & calculations setup
Submit antibody sequences or structures through the UI or API, with multiple input file types (FASTA, XLSX, PDB).
Explore several antibody formats, including Fv, scFv, VHH, Fab, bispecifics, ADCs, and custom constructs.
Set up calculations for conformational and charge (pH) sampling.
Structural ensemble generation & property calculations
Generate structural ensembles using stochastic titration and accelerated grand canonical sampling to capture conformational and protonation-state variability.
Compute 100+ global and residue-level properties/descriptors to assess antibody stability, solubility, charge distribution, and other developability-relevant features.
Simulate complex molecular systems, including non-natural amino acids and conjugated systems.
Developability & liability screening
Leverage a high-performing proprietary algorithm based on four determined rules for therapeutic antibody profiling against clinical-stage antibodies (Thorsteinson et al; mAbs 13 (2023) 219-235).
Perform large-scale, high-throughput screening to rank and prioritize antibody candidates early in discovery.
Automatically detect liability hot spots, including aggregation-prone regions, and PTMs.
Visualize surface features through standardized 2D protein patch maps.
Analysis & prioritization
Leverage sequence visualizer to assess annotated liabilities.
Identify germline sequences for potential back-mutations and compare residue-level properties across candidates.
Map detected liabilities back to the 3D structure to decide on the next optimization move.
Identify outliers within your reference dataset using customizable coloring rules and multiple plotting options for clear visual comparison.
Export ensemble-derived properties for ML model training or building applications.
