Immunoprecipitation analysis of GPIIb-IIIa complexes from CHO cells transiently cotransfected with cDNAs encoding GPIIIa and either normal or [Arg674]GPIIb. CHO cells were transiently transfected with cDNAs encoding GPIIIa and either normal or [Arg674]GPIIb. Surface (upper panel) or total (surface and intracellular, lower panel) labeling of cells was performed with biotin-NHS and the GPIIb-IIIa complexes were immunoprecipitated with anti-GPIIIa (P37) or anti-GPIIb (M3) MoAbs and processed as described in Materials and Methods.
