RFantibody: A New Approach for De Novo Antibody Design
Scientists have developed RFantibody, a deep learning-based method that enables the de novo design of antibodies and nanobodies with high experimental success rates. This tool is built upon the RFdiffusion framework and represents a significant advancement by focusing on the controllable generation of antibodies, a task that has historically been challenging for other methods. In one study, RFantibody successfully designed over 1 million VHH binders against 436 diverse targets, achieving specific and significant binding success for 45% of the targets.
How RFantibody Works
RFantibody is a generative model that produces antibody sequences and structures simultaneously for a given antigen. The model is built on the RFdiffusion framework and achieves its high success rates by leveraging informed sequence and structure conditioning information.
De Novo Design: RFantibody can generate entirely new antibody and nanobody binders for a given target, making it a powerful tool for exploring new therapeutic possibilities.
Controllable Generation: The model's success demonstrates that it is possible to design antibodies in specific formats without additional training of the underlying folding and language models.
High-Throughput Screening: The system was used to design and screen over 1 million binders, a scale that highlights its potential for large-scale therapeutic discovery.
