immunoassay
- n identification of a substance (especially a protein) by its action as an antigen
immunochemical assay
- n identification of a substance (especially a protein) by its action as an antigen
immunochemistry
- n the field of chemistry concerned with chemical processes in immunology (such as chemical studies of antigens and antibodies)
immunocompetence
- n the ability to develop an immune response following exposure to an antigen
immunodeficiency
- n immunological disorder in which some part of the body's immune system is inadequate and resistance to infectious diseases is reduced
immunoelectrophoresis
- n electrophoresis to separate antigens and antibodies
immunofluorescence
- n (immunology) a technique that uses antibodies linked to a fluorescent dye in order to study antigens in a sample of tissue
immunogen
- n any substance or organism that provokes an immune response (produces immunity) when introduced into the body
immunoglobulin
- n a class of proteins produced in lymph tissue in vertebrates and that function as antibodies in the immune response
immunoglobulin a
- n one of the most common of the five major classes of immunoglobulins; the chief antibody in the membranes of the gastrointestinal and respiratory tracts
immunoglobulin d
- n one of the five major classes of immunoglobulins; present in blood serum in small amounts
immunoglobulin e
- n one of the five major classes of immunoglobulins; present primarily in the skin and mucous membranes
immunoglobulin g
- n one of the five major classes of immunoglobulins; the main antibody defense against bacteria
immunoglobulin m
- n one of the five major classes of immunoglobulins; involved in fighting blood infections and in triggering production of immunoglobulin G
immunohistochemistry
- n an assay that shows specific antigens in tissues by the use of markers that are either fluorescent dyes or enzymes (such as horseradish peroxidase)
