V gene sequences and the percentage identity to the neutralizing VHH plotted (Fig. 5C, D).
Analysis of the DNA and encoded amino acid sequences of A14 and B9 revealed that the first two are clonal variants which aligned most closely to the germ line denoted VHH Vg (T Verrips, unpublished data) and that the sequence of B21 is highly divergent from both and also aligns to a different germ line
V gene sequence Vu.

The exact composition of germline
V gene sequences in an individual has been difficult to determine due to the highly repetitive nature of the genomic sequences encoding these segments, thus limiting our understanding of humoral immune responses.
