Have you ever heard of immunodiffusion?

No, what is that?

It's a lab technique used to see how antigens and antibodies react in a gel.

Root Explanation

Immunodiffusion → It is formed from "immunis" (from Latin, meaning exempt or free from) and "diffusio" (from Latin, meaning to spread out). The word describes a process where substances spread out in a medium, particularly in the context of immune reactions.

Memory Tip

Think of being 'exempt' ('immunis') from something and how substances 'spread out' ('diffusio') in a test — that's what immunodiffusion means.
