Intron A; Interferon Alfa-2B Recombinant, 25 million IU

Description (Brief)
Intron A is an injectible recombinant pharmaceutical used to treat hairy cell leukemia.
Recombinant pharmaceuticals are created by inserting genes from one species into a host species, often yeast or bacteria, where they do not naturally occur. The genes code for a desired product, and therefore the genetically modified host organisms can be grown and used as a kind of living factory to produce the product. In this case, genes coding for human white blood cell interferons are inserted into bacteria. Interferon is a substance that is naturally made by the body to fight infections and tumors. Bacteria produce the interferons, which are harvested and used as the active ingredient in Intron A.
Object consists of a cardboard box containing a second box, two glass bottles (one of the active pharmaceutical and one of the dilutent), and two product inserts.
