Differences in binding seen with the probe for 9-O-acetylated sialic acids, CHE-FcD, to mouse and to rat sections. As shown, 9-O-acetylated sialic acids are abundantly expressed in rat liver but not in mouse liver, although it is present on mouse red blood cells (right). It is also expressed on rat kidney glomeruli but not in the mouse kidney where it is present only on some medullary vessels. There is a different distribution in spleen from rat and mouse, and is present in rat lungs but not in mouse lungs; and diffusely in rat brain (left) and only in gray matter of mouse brain (right).
