This difference in binding ability to the two immunogens suggests the R2 immunogen may have driven the earlier stages of
affinity maturation of this lineage in llama 1, which resulted in clones that could also recognize 96ZM651.02 gp140 as the immune response progressed and the lineage developed breadth via mutations in the V gene region.
