Antibody Discovery and Optimization
Antibodies are highly precise and versatile molecules that help the immune system find and eliminate viruses, bacteria, and even cancer cells. Their enormous potential in therapeutics and diagnostics relies on their ability to bind targets with high specificity and be manufactured efficiently at scale. These are the most critical early stages of the drug development pipeline, where quickly securing the right antibody candidates can save years of development time and millions of dollars downstream.
Recent breakthroughs in artificial intelligence, from large language models to protein structure prediction, have enabled in silico antibody design and optimization, dramatically accelerating drug development so patients can access life-saving treatments faster.
Our End-to-End In Silico Solution
AbXLr8 is our platform that transforms raw sequencing data from your phage or yeast display experiments into a curated set of binders optimized for both binding affinity and developability.
Key Capabilities

Deep Library Exploration
- Comprehensive analysis of sequence and structural diversity across your antibody library
- Identification of candidates with optimal affinity and developability profiles
- Unbiased assessment of the full candidate landscape
AI-enhanced Design
- Generation of novel antibody sequences jointly optimized for affinity and developability
- Machine learning models that leverage sequence, structure, and surface information
