For this purpose, we tested [18F]1 in ApoE KO mice, a widely used murine model of atherosclerosis.[25] Six-week-old ApoE KO male mice (N=6) and C57BL/6 male control mice (i.e., a background strain of ApoE KO mouse, ApoE-wildtype control; N=6) were purchased from Jackson Laboratory (Bar Harbor, ME). Here, APOE is linked to atherosclerosis.
