How to Use BioPhi
Commercially Available Online Web Server
Use BioPhi online for antibody humanization and repertoire-based humanness evaluation.
BioPhi is an antibody design platform for humanization and humanness evaluation grounded in large natural antibody repertoires. The BioPhi paper combines Sapiens, a deep-learning model for sequence humanization, with OASis, a repertoire-based analysis that scores how human-like antibody sequence fragments appear relative to observed human antibodies.
On Neurosnap, researchers submit variable-domain sequences as paired heavy:light antibodies, single-domain nanobodies, or scFv-style heavy:light inputs. The service is most useful when a lead binder already exists and the next question is how to reduce immunogenicity risk while preserving developability and binding-relevant sequence features.
How BioPhi Works
Sapiens treats antibody humanization as a language-model problem over residue context, proposing substitutions that shift a non-human sequence toward the distribution of human repertoires. OASis complements that by examining short peptide fragments, especially 9-mers, against large human repertoire collections to identify sequence motifs that remain atypical after humanization.
On Neurosnap, BioPhi returns humanized candidates together with humanness summaries, alignment views, and repertoire-based curves that show where a sequence still departs from human antibody space. That combination is useful because it lets researchers inspect both the redesigned sequence itself and the local sequence liabilities that may matter for immunogenicity assessment, back-mutation decisions, or experimental rescue.
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.
Advancing Discovery with BioPhi on Neurosnap
Using BioPhi on Neurosnap could drastically accelerate antibody humanization and humanness-guided lead optimization from variable-domain sequences.
- Study-fit inputs: BioPhi accepts paired VH:VL antibodies, nanobodies, and scFv-style sequences, so existing discovery leads can be evaluated without reformatting them into a different design representation.
- Complementary modeling: Sapiens proposes humanizing substitutions while OASis measures how typical local sequence fragments are in large human repertoires, giving two distinct views of humanness.
- Actionable interpretation: Humanized candidates, alignment views, and humanness curves make it easier to spot which regions still look non-human and where targeted back-mutations may be needed.
- Research workflow fit: BioPhi is well matched to antibody lead optimization programs that need to balance immunogenicity risk reduction against preservation of binding-relevant sequence features.
