NK-cell depletion in the spleen of Apc^Min/+ mice. Representative dot plots of lymphocyte-gated splenic cells stained with antibodies against mouse CD3 and NK1.1. NK cells are defined as the NK1.1⁺ CD3^- population contained within the top left gate. The bottom right gate contains CD3⁺ T cells. Numbers indicate the percentage of lymphocytes that fall within the gates shown. Plots shown are representative of at least 3 different animals.
