Identifying The Best Antibodies Using X-Rays

Imagine you're going to a party where you only know a single person. While you've been friends with this person for a long time, you're concerned about them leaving you alone in a room full of strangers. Even though they promise they'll stick by your side, they immediately walk away from you upon entering the party to speak to someone else they know.
