Platelet HLA surface expression decreases with time after incubation at 37°C.
Platelets were incubated at 37°C in citrate buffer pH 6.2, for the indicated times, stained for expression of HLA (W6/32 and BB7.2 MoAbs) or CD41, and analyzed by cytometry. Background fluorescence is shown in white, staining with MoAbs in black.
