Key Terms

2. Antibody
An antigen-binding immunoglobulin, produced by B cells, that functions as the effector in an immune response.

3. Antigen
A foreign macromolecule that does not belong to the host organism and elicits an immune response.

4. Bioinformatics
The collection, classification, storage, and analysis of biochemical and biological information using computers especially as applied in molecular genetics and genomics.

5. Concentration
The amount of a specified substance in a unit amount of another substance.

6. ELISA- enzyme-linked immunosorbent assay
A quantitative in vitro test for an antibody or antigen in which the test material is absorbed on a surface and exposed either to a complex of an enzyme linked to an antibody specific for the antigen or an enzyme linked to an anti-immunoglobulin specific for the antibody followed by reaction of the enzyme with a substrate to yield a colored product corresponding to the concentration of the test material.

7. Enzyme
A protein serving as a catalyst; a chemical agent that changes the rate of reaction without being consumed by the reaction

8. Genome
The complement of an organism’s genes; an organism’s genetic material.

9. Medical Intervention
Any measure whose purpose is to improve health or alter the course of disease.

10. Outbreak
A sudden rise in the incidence of a disease.

11. Pathogen
A specific causative agent of disease.

12. Primer
A molecule (a short strand of RNA or DNA) whose presence is required for formation of another molecule (a longer chain of DNA).

13. Serial Dilution
A stepwise dilution of a substance in solution.

14. Solute
A substance dissolved in another substance.

15. Solution
A homogeneous mixture of two or more substances, which may be solids, liquids, gases, or a combination of these.

16. Solvent
A substance, usually a liquid, capable of dissolving another substance.

17. Substrate
The reactant on which an enzyme works.
