Vaccination and immunisation are two different processes. Vaccination only refers to the administration of a vaccine or toxoid, while immunisation is the process by which the body produces antibodies against the vaccine preventable diseases through administration of speÂ­cific vaccines. These are used to protect us and our domestic animals against viral and bacterial diseases.

Luciferase. Luciferase is a generic name for enzymes commonly used in nature for bioluminescence. The most famous one is firefly luciferase (EC 1.13.12.7). In luminescent reactions, light is produced by the oxidation of a luciferin (a pigment), sometimes involving Adenosine triphosphate (ATP) .The rates of this reaction between luciferin and oxygen are extremely slow until they are triggered by the presence of luciferase.uciferin and luciferase do not refer to a particular molecule. They are generic terms for a light-producing chemical and its associated regulatory compound, usually a protein. A wide variety of species regulate their light production using a luciferase.
