Flow cytometric analysis of K562/RhD cells transiently transfected with empty pcDNA3, pcDNA3/RhAG, and pcDNA3/K2 vectors.

Following double immunostaining experiments, simultaneous analysis of the RhD and RhAG antigen expressions (A,B) and of RhD and K2 antigen expressions (C,D) were performed on TPA-untreated cells (left panels) and TPA-treated cells (right panels).
