| umls-concept:C0003241 | skos:definition | MSH: Immunoglobulin molecules having a specific amino acid sequence by virtue of which they interact only with the ANTIGEN (or a very similar shape) that induced their synthesis in cells of the lymphoid series (especially PLASMA CELLS).,CSP: infection-fighting protein molecule in blood or secretory fluids that tags, neutralizes, and helps destroy pathogenic microorganisms such as bacteria or viruses and toxins; they are generally known as immunoglobulins, and are made and secreted by B-lymphocytes in response to stimulation by antigens; each specific antibody binds only to the specific antigen that stimulated its production.,NCI: A protein made by plasma cells (a type of white blood cell) in response to an antigen (a substance that causes the body to make a specific immune response). Each antibody can bind to only one specific antigen. The purpose of this binding is to help destroy the antigen. Some antibodies destroy antigens directly. Others make it easier for white blood cells to destroy the antigen.,NCI: | lld:umls |
