Genes encoding the mus musculus IgA HC constant region and the lambda LC constant region were fused with HC and LC variable region sequences to create complete HC and LC sequences. The HC and LC variable region is not modeled in this structure. Since authors have chosen not to provide complete sample sequence of the HC and LC variable region the UNKs were not included in the sequence.
