Antibody

Real World Example

Imagine you're at a crowded party and you need to find your friend who wore a unique red hat. Just like how you need to identify and approach that specific friend among many people, an antibody is a protein that specifically identifies and targets a particular antigen among many different substances in the body. In this analogy, the red hat represents the unique antigen that the antibody, produced by B cells, recognizes and binds to, ensuring that only the intended target is neutralized or destroyed, much like how you navigate the crowd to connect with your friend.
