ImmunoCheck

Comprehensive immunogenicity and developability assessment for VHH nanobodies. MHC-II epitope prediction, humanization scoring, and physicochemical profiling — in one API call.

MHC-II Epitope PredictionHumanization ScoringDevelopability Profiling

No API key required. Free for academic and commercial use.

Everything You Need to Assess Your Antibody

Three complementary analyses in a single endpoint. Built for bioinformaticians and antibody engineers.

MHC-II Epitope Prediction

Screen against 8 HLA-DRB1 alleles (EMA/FDA reference set). Identifies strong and weak binders, hotspot positions, and epitope density.

Humanization Scoring

Compares against 26 IGHV germlines. T20 score, framework identity, VHH hallmark residue analysis at positions 37, 44, 45, 47.

Developability Profiling

Full physicochemical profiling: MW, pI, GRAVY, instability index, aggregation hotspots, chemical liabilities (deamidation, oxidation, isomerization).

Fast & Lightweight

Results in under 3 seconds (without epitopes). No GPU required. Pure algorithmic analysis.

No API Key Required

Completely free to use. Rate limited to 5 requests/minute per IP. No registration, no sign-up.

OpenAPI / Swagger

Full interactive documentation at /docs. Auto-generated client libraries. JSON responses.
