Cell surface expression of PEN5 and PSGL-1 on NK cells. Flow cytometric analysis of highly purified NK cells using anti-PEN5, anti-CD56 (A) and anti-PSGL-1 (PL1) (B) mAb. Horizontal and vertical lines delineating positive and negative staining were set with appropriate negative control mAb. The percentage of cells in each quadrant is indicated at the top of each scatter profile.
