New cards

What are the four antigen-antibody reactions ?

Neutralization, agglutination, precipitation, and complement

3
New cards

Which antigen-antibody reactions are the most common and important?

Neutralization and agglutination

4
New cards

What is neutralization?

Antibodies block sites on viruses that elicit a specific reaction (phagocytosis)

5
New cards

What is agglutination?

Antibodies bind to antigens and create large cross-links, forming a huge complex that induces phagocytosis

6
New cards

What is precipitation?

Cross-linking between multiple antibodies and antigens, forming solid material that undergoes phagocytosis
