Immunoprecipitation of RhD and RhAG from K562 and K562/RhD/RhAG cells.
TPA-treated (+) and untreated (−) cells were incubated for 3 hours with [35S]-methionine. Cell lysates from K562 (W.T.) and K562/RhD/RhAG cells were used for immunoprecipitation with the MPC8 anti-Rh polyclonal antibody (PAb) (A) or the LA18.18 anti-RhAG mMAb (B) and Protein A–Sepharose. The isolated proteins were separated by 10% SDS-PAGE under reducing conditions. Low molecular weight proteins from Biorad were used as standards. Arrows indicate the 32-kd Rh and RhAG proteins.
