Antigens and antibodies

It is a molecule found in the surface of microorganisms that triggers immune response

It is a protective protein that the produced by B cells as a response to a specific antigens

A molecule on microorganisms that triggers immune response.

A protective protein produced by B cells to fight specific antigens.

Key for vaccine development, blood transfusions, and disease diagnosis.

Includes proteins, polysaccharides, and nucleic acids; lipids are mostly non-immunogenic.
