Lefranc, M.-P. et al., Dev. Comp. Immunol., 27, 55-77 (2003) PMID: 12477501 pdf with permission from Elsevier

CDR lengths [CDR1-IMGT.CDR2-IMGT.germline CDR3-IMGT] are according to the IMGT unique numbering for V-DOMAIN.

By default only the first allele (*01) is taken into consideration. Otherwise the next allele number is taken into account.
