Study Notes
Antigen Characteristics
- Larger molecular size is generally more effective for antigenicity
- Antigens with varied amino acid composition are more effective
- Antigens with multiple forms (heterogeneity) can pose a challenge for immune response
Haptens and Carrier Proteins
- Haptens are small non-protein molecules that can be recognized by the immune system and bind to antibodies
- Haptens lack immunogenicity, unable to initiate an immune response on their own
- Haptens can be bound to a carrier protein to trick the immune system into producing antibodies
Solubility and Immune Response
- Large insoluble antigens are more effective at inducing antibody production
- Solubility of the antigen affects its ability to initiate an immune response
