Scanning of B-cell epitopes in Protein Sequences using Variable Length Model



This tool allows users to predict antigenic regions in a protein or antigen that can stimulate specific class of antibodies. This page allows users to scan antigenic regions of desired length (from 4 to 20 residues) in protein sequences using variable length model. For more information see HELP page.

Select Threshold: User can customize threshold values for different types of B-cell epitopes
(higher threshold means high probability of correct prediction but poor coverage/sensitivity):

Threshold == Type of B-cell epitope
== IgG specific B-cell epitope
== IgE specific B-cell epitope
== IgA specific B-cell epitope
