   hello
   ANTIGEN:
   An antigen (from antibody generator) is a substance that prompts the generation of antibodies and can cause an immune response. We now know that the immune system does not consist of only antibodies. The modern definition encompasses all substances that can be recognized by the adaptive immune system. In the strict sense, immunogens are those substances that elicit a response from the immune system, whereas antigens are defined as substances that bind to specific antibodies. Not all antigens produce an immunogenic response (i.e. not all antigens are immunogenes), but all immunogens are antigens
   
   IMMUNOGEN
   A substance which is capable of eliciting (inducing) an immune response. An immunogen usually has a fairly high molecular weight (usually greater than 10,000), thus, a variety of macromolecules such as proteins, lipoproteins, polysaccharides, some nucleic acids, and certain of the teichoic acids, can act as immunogens.
   
   Hope it helps

   Actually as far as my knowledge gets tested
   
   Antigens and Immunogen are the same, they function in the same way, they look the same, and so on... Because, they are the same thing, immunogen is the synonym for the word antigen

   hello

   
   

   Antigen : any substance that can bint to an antibody or t cell receptor.

   
   

   Immunogen: any substance that can elicit an immune response.

   
   

    all immunogens are antigens but not all antigens are the immunogens, i.e. haptens.
