Titers of total IgG (•), IgG1 (○), and IgG2a (□) antidonor antibodies in BALB/c mice after receiving weekly transfusions of 106 donor platelet-pulsed BALB/c APC.
Fresh sera from the recipient mice at each transfusion week were titrated and analyzed for reactivity against donor cells by flow cytometry. The data are expressed as the mean ± SEM of the reciprocal titers. The insert shows rescaled data for the first 3 weeks of transfusion.
