(Learning Modules / Geography / Geography of health) An antigen on a virus surface causes production of antibodies.
(Humans as organisms) foreign invaders in the body that trigger an immune response
Substances (especially proteins) that are introduced or gain entrance into the blood and that stimulate the immune system to produce antibodies (or, in insects, other protective, lytic, or cidal substances), which react with and render the antigen ineffective.
proteins, usually foreign, which cause the bodies defense system to produce an antibody. Antigens may be food proteins, bacteria ,viruses or protozoa or cells from another individual(transplant).

Substances which are capable, under appropriate conditions, of inducing a specific immune response and of reacting with the products of that response, that is, with specific antibodies or specifically sensitised T-lymphocytes, or both. Antigens may be soluble substances, such as toxins and foreign proteins, or particulates, such as bacteria and tis...Found on http://www.encyclo.co.uk/local/20973
Molecules carried or produced by microorganisms that initiate antibody production; mostly proteins or proteins combined with polysaccharides.Found on http://www.emc.maricopa.edu/faculty/farabee/biobk/biobookglossa.html
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.Found on http://www.aacr.org/home/survivors--advocates/glossary-of-cancer-terms-k-z.
