HLA class I antigen expression by immunomagnetic isolated myeloid leukemic and autologous normal myeloid cells. Untouched autologous normal cells (top row) were stained with anti-CD3 (black) and anti-CD33 (white) mAbs (A); anti–HLA-A mAb LGIII-147.4.2 (open, solid line), anti–HLA-B mAb B1.23.2 (black), and control mAb (open, dotted line) (B); and with anti–HLA-A, -B, -C mAb W6/32 (black) and control mAb (white) (C). Untouched leukemic cells from a patient with AML (bottom row) were stained with anti-CD3 (white) and anti-CD33 (black) mAbs (D); anti–HLA-A mAb LGIII-147.4.2 (open, solid line), anti–HLA-B mAb B1.23.2 (black), and control mAb (open, dotted line) (E); and with anti–HLA-A, -B, -C mAb W6/32 (black) and control mAb (white) (F). Forward/side scatter dot plots of the isolated cell populations are shown on the left.
