10 Questions
What is the ideal molecular size for an antigen to work well?
Large
What is the significance of having varied amino acids in an antigen's composition?
It enhances the antigen's immunogenicity
What challenge do antigens with multiple forms pose?
They are more difficult to work with
What is the characteristic of haptens that makes them different from antigens?
They lack immunogenicity
Why are large insoluble antigens often preferred for causing an antibody response?
They are more effective at initiating an immune response
Which of the following factors is not a determinant of an antigen's ability to initiate an immune response?
Immunogenicity
What is the main advantage of binding a hapten to a carrier protein?
To enable the hapten to initiate an immune response
Which of the following antigens would be most likely to cause an antibody response?
A large, insoluble protein
What is the main challenge posed by antigens with multiple forms?
They may not be recognized by the immune system
Why is it important for an antigen to have a varied amino acid composition?
To increase its ability to initiate an immune response
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
