Figure 1. IGVH and IGJH usage in bone marrow (BM) and spleen (SP) of naïve and spleen lymphocytes in immunized (IM) rabbits. (A) The bars represent the % of heavy chain sequences derived from germline IGHV genes 1S40, 1S45 and 1S69. Germline genes contributing > 5% of the V-gene repertoire in at least one sample are shown. (B) The bars represent the % of heavy chain sequences containing germline IGHJ genes IGHJ2, IGHJ3 and IGHJ4. Germline genes contributing > 2% of the V-gene repertoire in at least one sample are shown. See Table S3 for a complete list of all the genes.
