Expression of NK cell-specific surface markers on sorted NK cells. Isolated splenic NK (NK1.1-positive, CD49b-positive, CD3-negative) cells from wild-type mice and mice null for CD39 were characterized. Surface markers, in general, did not differ between wild-type and mutant NK cells, except KLRG1. Also, CD39-null NK cells expressed decreased levels of CD27 as compared to the wild-type.
