Substances that cause an immune response in the body. The body "sees" the antigens as harmful or foreign. To fight them, the body produces antibodies, which attack and try to eliminate the antigens.
substances that activate the immune system. Any substances that as a result of coming into contact with appropriate cells, induces a state of sensitivity and/or immune responsiveness after a latent period, and which results in a demonstrable way with antibodies with antibodies and/or immune cells of the sensitized subject.
substances that provoke an immune response in the body. The body produces antibodies to fight antigens, or harmful substances, to try to eliminate them.
substances which stimulate the formation of antibodies
Substances that cause an immune response in the body; identifying substances or markers on cells. The body produces antibodies to fight antigens, or harmful substances, and tries to eliminate them.
Substances that induce the formation of antibodies that interact specifically with them.
substances that are foreign to a person's own body and cause immune responses to occur when they are identified by T cells and B cells.
any foreign substance in the body that causes the creation of an antibody.
the immune-stimulating polysaccharides on the surface of cells.
Agents capable of stimulating the formation of antibodies.
Foreign substances within the body that are recognised by the immune system and are capable of inducing an immune reaction.
Compounds that stimulate production of antibodies.
substances, usually harmful, that when entering the body stimulate the immune system to produce antibodies.
Substances that cause the immune system to make a specific immune response. An example would be a protein only found on tumor cells. Another example would be a murine antibody, which is derived solely from mouse proteins and therefore is viewed as foreign by the host (human) body.
a foreign substance that stimulates the formation of antibodies in the body.
Foreign bodies, usually protein molecules, which provoke the formation of antibodies.
A substance, often part of Microorganisms that causes disease, which can give rise to an immune response.
Foreign substances (e.g. bacteria or viruses) in the body that are capable of causing disease. The presence of antigens in the body triggers an immune response, usually the production of antibodies.
A foreign molecule that stimulates the production of antibodies.
Molecules carried or produced by microorganisms that initiate antibody production; mostly proteins or proteins combined with polysaccharides.
Foreign substances in the body that are capable of causing disease. The presence of antigens in the body triggers an immune response, usually the production of antibodies. Antigens may be soluble substances, such as toxins and foreign proteins, or particulate, such as bacteria and tissue cells; however only the portion of the protein of polysaccharide molecule known as the antigenic determinant combines with antibody or a specific receptor on a lymphocyte.
Any foreign or perceived foreign protein that when entering the body's chemistry stimulates the production of an antibody.
A foreign substance that can stimulate an immune response when introduced into the body.
large molecules, often found on the outside of germs which cause an immune response
a molecule with a specific configuration that is recognized by the immune system; usually part of a protein or sugar. It stimulates the formation of a specific antibody and can elicit an allergic reaction, or otherwise trigger an immune response.
Any substance capable of stimulating an immune response, usually a protein or large carbohydrate that is foreign to the body.
Substances that activate the immune system and react with antibodies produced by the immune response.
Substances that are recognised by the immune system as 'foreign' and which stimulate the immune system into action. Antigens include bacteria, viruses, chemicals, etcetera.
Proteins in the body that are recognized by the immune system and can produce an immune response.
A substance that when introduced in the body stimulates the production of an antibody.
substances capable of inducing an immune response.
Substances which are capable of inducing a specific immune response.
Any biological substance that can stimulate the production of, and combine with, antibodies. Variances in human antigens can be used to identify individuals within a population.
Foreign substances, such as bacteria or viruses, that cause the immune system to make specific antibodies. See antibodies.
foreign invaders in the body that trigger an immune response Humans as organisms
A toxin, foreign protein particle or bacteria that can trigger an immune response.
Specific structures on the cell surface of bacteria, viruses or fungi. If the body is attacked by such pathogens, the plasma cells developed from the B-lymphocytes form antibodies.
Substances that are recognized by the immune system and cause the immune system to create antibodies.
