PEPVAC is a tool to assist in the development of multi-epitope vaccines. It is optimized for this task by predicting peptides with the ability to bind to several human leukocyte antigens that have similar peptide binding specificity.
Protegen is a web-based database and analysis system that curates, stores and analyzes protective antigens. Protegen includes basic antigen information and experimental evidence curated from peer-reviewed articles. It also includes detailed gene/protein information (e.g. DNA and protein sequences, and COG classification). Different antigen features, such as protein weight and pI, and subcellular localizations of bacterial proteins are precomputed.
