Phenogram of ruminant immunoglobulin κ variable genes. Sequences corresponding to the V region but excluding CRD3 were aligned and phylogenetically analyzed as described in the methods. IGLV6 was used as an outgroup. The ovine sequences 1, 2.1, 2.2, 2.3, 3 and 4 (AF038133–AF038138) are derived from cDNA .
