Release notes - 4.0 (Mar 18, 2026)
-
New Web Tools!
- B Cell Prediction - Sequence Based: Starting from a protein sequence, this tool provides a variety of methods for predicting linear B cell epitopes. This tool includes BepiPred 3.0 as well as amino-acid scale-based methods (Chou & Fasman, Emini, Karplus & Shulz, Kolaskar & Tongaonkar, Parker) that use amino acid properties such as hydrophobicity, flexibility, and side chain protrusion to predict antigenicity.
- B Cell Prediction - Structure Based: Starting from a solved or predicted protein structure, this tool provides the Discotope 3.0 and ElliPro methods to predict antigenic regions.
