Flow cytometric analysis of fresh splenic NK cells from different strains of mice.

C57BL/6 (H2^b, A), BALB/c (H2^d, B), C57BL/10 (H2^b, C), and B10.D2 (H2^d, D). NK cells were stained with pan NK marker DX5, anti-Ly-49A mAb YE1-48, and anti-Ly-49G2 mAb 4D11. The Y-axis and X-axis represent fluorescence intensity of phycoerythrin (PE)-conjugated 4D11 and fluorescein isothiocyanate (FITC)-conjugated YE1-48 antibodies, respectively.
