Antibodies types

Antibodies are disease-fighting proteins in the body that play a crucial role in the immune system. Much like a search battalion, antibodies recognize infectious invaders such as bacteria and viruses and help the body eliminate them. Antibodies develop in response to an infection or enter the body passively through vaccination. An antibody is sometimes called an White blood cells called plasma cells produce antibodies during the course of an infection. A single plasma cell can secrete several Keep reading to learn more about antibodies, including how they work, the types, and more. Share on Pinterest bojanstory/Getty Images Antibodies are Y-shaped proteins. The base of the antibody (the vertical leg of the Y) helps it communicate with other components of the immune system. The tip of the antibody (both arms) can bind to foreign invaders. These invaders, either in whole or in part, are called Each antibody has a total of four protein chains: two light and two heavy chains, arranged in a light-heavy-heavy-light structure. The light chains weigh approximately 25 kilodaltons (kDa), and the heavy chains about 50 kDa. The tip of the antibody consists of both light and heavy chain portions. Scientists call this tip the “antigen binding site” or Antibodies have a 3D structure, which helps them bind to Antibodies develop during an infection or in response to a vaccine. Each antibody is specific and has one of two precise tasks: tag an invader for destruction by other immune cells, ...

Comic Relief Activity Students will create a humorous comic strip summarizing what they have learned about antibodies. Materials • Transcripts of the video lesson • Art supplies: art paper, markers, colored pencils etc. Instructions • Conduct a discussion in which you lead your students to consider what it might be like to be an antibody. Use anthropomorphic language to encourage your students to really think about what they have learned from the perspective of an antibody. For example: • So, do you think the little antibody guy is just hanging out all the time waiting to be called to a fight, or can you picture him or her marching around the body totally on guard 24/7? • After your students have warmed to the idea of viewing the body from the antibodies' perspective, instruct them to create a comic strip, or book, that teaches the reader all about what antibodies are and how they work. The comic must: • Be from the perspective of the antibody. • Include all the information given in the lesson. • Including all the definitions and all five of the types of antibodies. • Be creative (not just an academic repeat of the lesson). • Allow your students to use external material to re...
