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

B10.BR (H2^k, A), B10 × B10.D2 (H2^bxd,B), B10.D2 × B10.BR (H2^dxk, C), and B10 × B10.BR (H2^bxk, 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 PE-conjugated 4D11 and FITC-conjugated YE1-48 antibodies, respectively.
