A-Alpha Bio is a biotechnology company using synthetic biology and machine learning to measure, discover, predict, and engineer protein-protein interactions. We pursue our mission of improving human health through an internal therapeutics pipeline and by partnering with industry-leading pharmaceutical and technology companies.

Current approaches for measuring protein-protein interactions are insufficient for many drug development applications due to low accuracy or throughput. We are a team of synthetic biologists, structural biologists, and next-generation sequencing experts who have come together to remove this industry-wide bottleneck. Our proprietary experimental platform, AlphaSeq, generates high-resolution data to discover rare and effective antibodies, identify degradable neo-substrates for molecular glues, and generate massive protein-protein interaction datasets to map the protein binding landscape. Our AlphaBind platform then leverages these data to train predictive machine learning models to further accelerate the discovery and optimization of high-impact therapeutics.

A-Alpha Bio, Inc. was founded in 2017 as a spinout from the University of Washington's Institute for Protein Design and Center for Synthetic Biology and is based in Seattle, Washington.

We are excited to participate in the 2nd Annual Molecular Glue Drug Development Summit in Boston this week! During the summit, we will share our latest work on applying AlphaSeq and AlphaBind for molecular glue discovery. 

In his talk, A-Alpha Bio Co-Founder and CTO Randolph Lopez will showcase how we use our platforms to improve the efficiency of identifying latent E3 ligase-target interactions using high-throughput experiments and machine learning. 

A-Alpha Bio Senior Scientist Arpita Sen will present a poster on how our platforms enable a high-throughput approach to discover novel glueable ligase-target pairs. 

If you’re attending, catch Randolph’s talk and stop by Arpita’s poster on February 1st to learn more.

We are excited to share the results of our recent collaboration with Google and Lumen Bioscience! 

With funding from the Bill & Melinda Gates Foundation, we’ve used AlphaSeq and machine learning (ML) to generate highly diverse single-domain antibodies that bind and neutralize SARS-CoV-2 variants with broad cross-reactivity. 

Through multiple iterations of AlphaSeq data generation, ML model training, and antibody design, we generated thousands of antibody variants showing enhanced binding against diverse SARS-CoV-2 strains. The most promising antibody candidates were expressed recombinantly and evaluated with biolayer interferometry and viral neutralization assays, demonstrating up to 100-fold improvement in binding and neutralization compared to the parental antibody.

The end result is twofold: (1) therapeutic variants showing potent neutralization of diverse viral variants, and (2) an ML approach that can predict binding across vast regions of sequence space and may help future-proof therapeutics against rapidly evolving pathogens.
