|
A molecule that can be covalently linked to a non-immunogenic antigen to make it an immunogen is called
|
|
adjuvant
|
|
|
carrier
|
|
|
hapten
|
|
|
mitogen
|
Explanation:
Detailed explanation-1: -Hapten is a molecule that reacts with specific antibody but is not immunogenic by itself, it can be made immunogenic by conjugation to a suitable carrier.
Detailed explanation-2: -Unlike antigens, haptens require an additional molecule before they are able to elicit an immune response. These additional molecules are called “carriers” and are often proteins to which the hapten binds to tightly; this is usually a covalent bond.
Detailed explanation-3: -Adjuvants. To enhance the immune response to an immunogen, various additives called adjuvants can be used. When mixed and injected with an immunogen, an adjuvant will enhance the immune response.
