Association between VH1-69 gene usage, CDR-H3 length and number of somatic mutations.

aMean (# of MAbs). CDR-H3 length and SM were tested between ChI MAbs using VH1-69 and those that do not; CDR-H3 length was significantly different (pH1-69.bTt, Tukey test. Letters denote conditions (rows) that differ at the 5% level in a posteriori comparisons among MAbs not using VH1-69. Again, statistical comparisons were made only for those not using VH1-69, due to the low numbers of SAD and AcI MAbs that used VH1-69.
