Cotransfection of FcɛRIγ with CD4/PIR-A3 enhances cell surface expression in 293T cells. Fifty nanograms of pcDNA3 (□), CD4/PIR-A3 (▩), or CD4/PIR-A3R632L (▪) cDNA were transiently transfected in the absence or presence of 500 ng murine FcɛRIγ cDNA. Twenty-four hours later, the cultures were labeled with PE-conjugated anti-human CD4 for flow cytometric analysis.
