What are antigens?

1 doctor answer
Dr. Ed Friedlander
43 years experience in Pathology
Parts of molecules: Anything that one creature's immune system recognizes (rightly or wrongly) as foreign and reacts against can be considered an antigen. Usually these are sequences within proteins. We pathologists use antibodies against normal components of human tissue made by other animals to tell what's in cells we are examining to tell what they are; blood bankers must choose donor units with the right antigens.
