Here's CD47, conjugated to a fluorophor (when you have a cell covered in a conjugated antibody, it fluoresces when exposed to laser light - this is done so that an instrument called a flow cytometer can identify cells).

Of course, to get CD47 depletion, you'd probably want an antibody that isn't conjugated (functional grade):

Also, some more help on the terminology: CD47 (and most, if not all molecules that fall under the Cluster of Differention [CD] nomenclature) vary on a per-species basis. So an antibody that targets CD47 in mice is not going to stick to human CD47. "Anti-" in this context means that the antibody in question will stick to specific molecule in the species that comes after the "anti-".
Note what it says on the bottom of the page. That's there because of regulations.
