(A) Alignment of anti-Rh(D) λ light chains to their nearest germline V and J genes and (B) alignment of the 10 V_λ germline genes used shows the use of a diverse set of variable region genes derived from multiple families. However, all of the clones use the identical J_λ gene segment. Nomenclature for the clones is similar to that for heavy chains but uses the letters J through S. The key is the same as that used in Fig2A. Genbank accession numbers for anti-Rh(D) λ light chains are listed in the Appendix.
