Enzyme-linked immunosorbent assay (ELISA): ELISA stands for “enzyme-linked immunosorbent assay.” This is a rapid immunochemical test that involves an enzyme (a protein that catalyzes a biochemical reaction). It also involves an antibody or antigen (immunologic molecules). ELISA tests are utilized to detect substances that have antigenic properties, primarily proteins (as opposed to small molecules and […]
- Enzymes, yellow
Enzymes, yellow: A group of respiratory enzymes that catalyze reactions in the body permitting cells to respire or breathe, in other words, use oxygen. These biochemical reactions are termed oxidation-reduction reactions. The first yellow enzyme was discovered by the German biochemist Otto Heinrich Warburg (1883-1970), a pioneer in research on the respiration of cells, who […]
- EOG
EOG: Electro-oculography. A type of electrophysiologic retinal testing.
- EOS
EOS: The gene for familial eosinophilia. EOS has been mapped to chromosome region 5q31-33 containing the cytokine gene cluster which includes the genes for interleukin-3 (IL-3), interleukin-5 (IL-5), and granulocyte colony-stimulating factor (G-CSF), and all of which are thought play roles in the development, proliferation, and activation of eosinophils.
- Eosinophil
Eosinophil: A normal type of white blood cell that has coarse granules within its cytoplasm. Eosinophils are produced in the bone marrow and migrate to tissues throughout the body. When a foreign substance enters the body, other types of white blood cells (lymphcytes and neutrophils) release substances to attract eosinophils and then release toxic substances […]
