HLA-A*24 and HLA-A*32, but not HLA-A*23 or HLA-A*25, are expressed on lymphocytes. PBMCs from healthy donors genotyped for HLA-A*24, HLA-A*32, HLA-A*23, or HLA-A*25 in combination with Bw6/Bw6 or genotyped for HLA-B*38 or HLA-B*52 were stained with fluorescein isothiocyanate-conjugated anti-HLA-Bw4 antibody. Mean fluorescence intensity (MFI) of the indicated Bw4⁺ HLA-A allotype is depicted among CD3⁺CD56⁻ (T cells), CD3⁻CD56⁺ (NK cells), and CD19⁺ (B cells) cells.
