Antibodiesare special protein molecules that the immune system produces in response to antigens. Andantigensare substances that can stimulate the body’s production of antibodies. Now, there are different types of antigens, but, for our purposes here, let’s zoom in on foreign, disease-causing ...
Antigens and antibodies are essentially at war with each other inside most human bodies. Antibodies, also known as immunoglobulins, are Y-shaped molecules found in the blood that fight against foreign substances known as antigens. Antigens are proteins or polysaccharides of bacteria, chemical, or ...

Antibodies in the immune system are proteins that are produced by certain white blood cells called lymphocytes. These proteins are specifically programmed to attack and kill invading viruses, bacteria or other foreign microbes, called antigens. There are five subtypes of antibodies, or types of ...
Whether you’ve already been administered an antibody test or hope to get one in the future, here’s what you need to know about whether to trust the results. What are antibodies? When your body is exposed to an antigen — or outside substance including viruses, bacteria, and certain chem...
To make these antibodies, a mouse is exposed to anantigen, and cells are collected from the spleen. These cells are cultured with cells from amyeloma, a cancer of theplasmacells, to create ahybridomawhich will endlessly replicate itself. The replications can be tested to find the cells which...
Monoclonal antibodies are laboratory-made antibodies that act like your body’s natural antibodies. They are engineered for specific purposes. Cancer-fighting monoclonal antibodies go after cancer cells. For autoimmune diseases, monoclonal antibodies can interfere with inflammatory proteins, such as those ...
