DIGIT: a database of immunoglobulin variable domain sequences annotated with the type of antigen, the germline sequences and pairing information between light and heavy chains. User submitted sequences can be blasted against the data base and annotated with the Kabat-Chothia numbering scheme, the location and canonical structures of the CDRs and the mutations with respect to the germline. A 3D model can also be obtained via our 3D modeling tool for immunoglobulin variable domains (PIGS).
