Figure S1. The VH147 Ig transgene excludes endogenous Ig rearrangement. Spleens from tg neg B6.K, tg neg BALB/c, or VH147 tg B6.K mice were stained for IgM allotype. In the VH147 tg mice, tg Ig is IgM^a, whereas endogenously rearranged Ig is IgM^b. The percentages indicate cells in each respective quadrant. n = 8 mice of each genotype.
