Measure, Discover, Engineer

Protein-protein interactions govern all of biology and are crucial for understanding and combating disease.

However, a lack of abundant and high-quality protein-protein interaction data limits our understanding and ability to treat cancers, infectious diseases, neurological diseases, and more.

A-Alpha Bio generates the high-resolution data needed to discover rare and effective antibodies, identify degradable neo-substrates, engineer protein interfaces, and fuel predictive machine learning models to further accelerate the discovery and optimization of high-impact drugs.
