# AlphaProteo designs high-affinity protein binders

Full title: AlphaProteo designs high-affinity protein binders, including the first AI-designed VEGF-A binder

DeepMind's AlphaProteo generated protein binders for 7 targets with 9–88% experimental success rates (88% for BHRF1) and 3–300× better affinities than prior methods. It produced the first successful AI-designed binder for VEGF-A.

## Key facts
- Experimental binding success 9–88% across 7 targets
- Affinities 3–300× better than the best previous methods on several targets
- Technical report, not peer-reviewed at announcement

## What happened

DeepMind released a binder-design system and reported wet-lab results from partner labs.

## Why it matters

High one-shot success rates cut the months of screening normally needed to find a binder.
