The pattern of RhD peptides that stimulate PBMCs from alloimmune donors to proliferate is reproducible.

Proliferative responses of PBMCs from alloimmune donor 12 against the panel of peptides spanning the RhD protein were compared on 2 occasions (A and B) 2 months apart. The broken line indicates the level of proliferation assumed to represent a positive response (the higher of SI = 3 or cpm = 1000).
