Free & Open API
ImmunoCheck
Instantly assess MHC-II epitopes, humanization, and developability of any antibody — no API key required.
MHC-II Epitope PredictionHumanization ScoringDevelopability Profiling
No API key required. Free for academic and commercial use.
Everything You Need to Assess Your Antibody
Five validated analyses, one API call.
MHC-II Epitope Prediction
Identify immunogenic peptides binding to common HLA-DR/DP/DQ alleles.
Humanization Scoring
Germline identity, T20 score, framework hallmark residue checks.
Developability Profiling
MW, pI, GRAVY, instability index, aggregation hotspots, sequence liabilities.
Fast & Lightweight
Sub-second response time. No ML inference, just rigorous biophysics.
No API Key Required
Open access for academic and commercial use. Rate-limited at 5 req/min.
