Antibodies and Antigens


Our bodies have mechanisms to protect us from foreign invaders.

What do you know about antibodies and antigens? This guided lesson will help you better understand how these molecules interact and why this is important to our health.

This website has the materials you will need to get started in our exploration of antigens and antibodies. To begin, download the handout and start on the Introduction page.

Learning objectives were adapted from Suchman et al. 2018.

  • Describe how antigens and epitopes are related using examples of virus antigens.

  • Explain why some antibodies that do not bind to epitopes are produced.
