How to Use ParaSurf
Commercially Available Online Web Server
Use ParaSurf online for antigen-agnostic paratope prediction across antibody CDR and framework residues.
ParaSurf predicts paratope residues directly from antibody or nanobody structure without requiring the antigen. The Bioinformatics paper is notable because it does not restrict binding-site prediction to CDR loops alone; instead, it models the entire Fab/Fv molecular surface, allowing framework residues with real binding contribution to be identified as well.
On Neurosnap, researchers upload an Input Structure containing the antibody variable region and receive residue-level and atom-level binding-site predictions. This makes the workflow useful for paratope mapping, humanization review, mutagenesis planning, and rapid inspection of antibody candidates before docking or experimental epitope studies.
How ParaSurf Works
ParaSurf builds a surface-based representation that combines geometric shape, chemical information, and electrostatic features, then processes that representation with a hybrid 3D ResNet-Transformer architecture. The model is designed to capture both local interaction cues and larger surface context, which is why it can recognize paratopes that extend beyond canonical loop definitions.
A second practical strength is that the model is antigen agnostic. Researchers do not need a co-complex to get a first-pass paratope hypothesis, which is important in early antibody discovery and optimization settings where only the antibody structure is available.
On Neurosnap, the residue- and atom-level views should be used together. High-confidence surface patches can guide mutagenesis, docking restraints, or developability review, while broader predicted binding regions can help identify framework participation that would be missed by a CDR-only assumption.
What is Neurosnap?
Neurosnap is the leading platform for bioinformatics and computational science focused on expanding access to powerful modeling and simulation tools. Because many state-of-the-art machine learning systems remain complex to install, configure, and scale, Neurosnap offers a clean, browser-based workspace that removes the burden of infrastructure management, dependency conflicts, and command-line tooling.
Built for biologists, chemists, and cross-disciplinary scientists, the platform enables advanced computational workflows without requiring expertise in software engineering or cloud architecture. Researchers can launch analyses through an intuitive interface, connect programmatically through a comprehensive API, and rely on automated resource management to scale workloads efficiently. By taking care of the underlying compute and operational complexity, Neurosnap allows teams to devote their energy to scientific progress and faster iteration. Security and data protection remain foundational principles, with clear safeguards outlined in our Terms of Use and Privacy Policy to ensure your work stays protected.
