good immunogens |
|
|
APC- antigen presenting cell |
heterogeneous group of immunocompetent cells that mediate the cellular immune response by processing and presenting antigens to the T cells |
|
|
Hapten |
Non immunogenic materials that when combined with a carrier create a new antigenic determinants |
|
|
Carrier |
responsible for antigen to give its size |
