Antigen Individual

An individual antigen is an agent homogeneous in molecular structure and free from admixtures of other antigenic substances. This concept refers to molecules that can be recognized by the body's immune system and trigger an antibody response.

Individual antigen plays an important role in immunology and is used in medicine to develop vaccines and diagnose infectious diseases. It can be obtained from various sources such as bacteria, viruses, fungi and other microorganisms.

Once an individual antigen is obtained, antibody molecules produced by the immune system can be used to determine the presence of that antigen in the body. This can be used to diagnose infectious diseases such as tuberculosis, hepatitis, malaria and others.

Also, an individual antigen can be used to develop vaccines. Vaccines are based on an individual antigen and contain it in a form that does not cause a reaction from the immune system, but when introduced into the body causes the production of antibodies that protect against infection.

Overall, individual antigen is an important tool in medicine and immunology, and its use can help fight infectious diseases and develop more effective vaccines.

**Individual antigen** - A., is something that can be classified as an antigen and have antigenicity. This concept is inextricably linked with the ability of any antigen (intracellular product) to cause an immune response. Such a response can develop in both infectious and non-infectious lesions. These are, for example, tissue transplants. Possessing the ability of antigenicity, they can cause a specific immune response and die as a result of its manifestations, but as an alternative, they can cause resorption.
