Epitope density profiles of selected normal D, partial D, and weak D samples.

On the abscissa, ranges of epitope densities (sites/cell) as detected by various anti-D are given using a logarithmic scale. On the ordinate, the number of anti-D representing the particular ranges of sites/cell are shown. The following phenotypes are depicted: Panel A, normal CcDee sample; Panel B, DHMi; Panel C, D^IV type III; Panel D, weak D type 3; Panel E, weak D type 4.0; Panel F, weak D type 7.
