Antibody discovery now drops from weeks to hours using artificial intelligence and cryo-electron microscopy, according to a study in Science Advances. “This represents a paradigm shift in how we discover antibodies,” said Andrew Ward, professor at Scripps Research.
Ward added that the method “could be game-changing for pandemic preparedness and therapeutic development.” The accelerated pipeline is positioned to speed drug programs at the earliest, most time-critical stages.
Inside Scripps’ Structure-to-Sequence Pipeline
The Scripps method, called Structure-to-Sequence (STS), marries high-resolution cryoEM imaging with the AI tool ModelAngelo. Researchers analyze the structure of immune responses, then match them to antibody sequences in genetic databases.
By removing guesswork in early screens, STS identifies promising candidates in under a day. The draft notes proof-of-concept in animal models, with flu-focused work demonstrating practical momentum and laying groundwork for broader use.
Pandemic Use Cases: From Influenza to HIV
Speed matters in the first days of an outbreak. The STS approach directly inspects how antibodies bind to targets, enabling quicker selection of therapeutic leads. That capability is relevant for influenza and HIV, where viral evolution complicates discovery.
Scripps positions the pipeline as a preparedness tool: faster triage of antibody candidates, clearer prioritization, and earlier movement into preclinical testing. The result is a shorter path from discovery to formulation when timing is critical.

- STS (AI + cryoEM): Hours, often under a day.
Operational Considerations and Risks
The team acknowledges scaling challenges. Wider deployment will require research partnerships, integration with existing health infrastructures, and consistency across labs. The approach must also align with downstream manufacturing and regulatory steps, which the draft does not detail.
Still, the structural readouts paired with AI guidance suggest a repeatable framework. If adoption spreads, institutions could coordinate rapid candidate identification and move promising antibodies into development faster than current norms.
What Comes Next for Scripps
Scripps plans to expand collaborations to sharpen the method and extend disease coverage. Early animal-model evidence supports feasibility, and internal partnerships aim to refine formulations that can translate into therapies.
The authors frame STS as a foundational improvement rather than a one-off tool. As the method matures, it could standardize early discovery across pathogens and support global readiness for future medical emergencies.
Quick Takeaways
- Scripps’ STS pipeline pairs cryoEM with AI to find antibodies in hours, not weeks.
- Early data in animal models show feasibility; expansion and scaling remain open.
- Faster discovery can compress the path to therapeutics during outbreaks.
