10 Questions
What is the significance of a larger molecular size in an antigen?
It increases the ability to initiate an immune response
Why is it important to have varied amino acids in an antigen's composition?
It enhances the antigen's ability to initiate an immune response
What is the difficulty posed by antigens with multiple forms?
They are difficult to work with due to their heterogeneity
What is the purpose of binding a hapten to a carrier protein?
To enable the hapten to initiate an immune response
What is the advantage of using large insoluble antigens?
They are better at causing an immune response
What is a desirable characteristic of an antigen's composition?
Varied amino acids
What makes haptens unable to initiate an immune response on their own?
Lack of immunogenicity
Why do large insoluble antigens tend to be more effective at causing an immune response?
Because of their size and insolubility
What is a potential issue with using an antigen that has multiple forms?
The immune system may have difficulty recognizing it
What is the benefit of binding a hapten to a carrier protein?
To trick the immune system into recognizing the hapten
Study Notes
Antigen Selection for Inoculation
- Molecular size of the antigen is a critical factor, with larger molecules being more effective.
- Antigen composition should include a variety of amino acids for optimal results.
- Antigen heterogeneity can pose a challenge, as multiple forms of a particular antigen can make it difficult to achieve an effective immune response.
- Haptens, small non-protein molecules, possess antigenicity but lack immunogenicity, and can be used to trick the immune system into producing antibodies by binding them to a carrier protein.
- Solubility of the antigen is also an important consideration, with large, insoluble antigens being more effective at inducing an antibody response.
