Determinants of antigenicity

Antigenicity is the ability to combine specifically with the final products of the responses i.e. secreted antibodies and/or surface receptors on T cells. All molecules having the property of immunogenicity also have the property of antigenicity but the reverse is not true. Some small molecules are antigenic but they are not able to induce a … Read more

Differences between active and passive immunity

  S.N Active immunity Passive immunity 1. Produced actively by the immune system of the host. Received passively by the host and the host immune system does not participate. 2. Induced by infection or by contacts with immunogens. Conferred by introduction of ready-made antibodies. 3. Immune response is durable and effective. Immune response is short … Read more

Differences between antigens and antibodies

S.N Antigens Antibodies 1. Commonly called “antibodies generating chemicals” or immunogens. Commonly called immunoglobulins. 2. Both proteinous or polysachharides. Always proteinous in nature. 3. They are present on the cell membrane. They are present in the plasma. 4. These stimulate the immunity of the body. These protect the body from infections. 5. May be a … Read more
