Macromolecules
& Synthetic Antigens
Types of antigens: - continued
3.Macromolecules
˜induce a
humoral immune response
˜larger than
the antigen-binding portion of antibody
˜contains
multiple epitopes that will bind with idiotope
4.Synthetic
˜chemically
synthesized short peptides
˜sequence of
amino acids from known infectious agents
˜act as
haptens
˜used as
vaccines but limited use due to:
Udoes not
induce immunologic memory against hapten but rather against carrier molecule
