Is interferon a biological product?

It is a biological product, generally produced by genetic engineering, called recombinant interferon.

Interferon is a kind of protein with broad-spectrum antiviral, antitumor and immunomodulatory activities, which has important value in disease diagnosis, prevention and treatment, and has attracted great attention from medical and biological circles. The traditional blood-borne interferon extracted from animals, due to limited sources and technical funds, can not be synthesized in large quantities, which has become a thing of the past. With the development of biotechnology, interferon can be produced on a large scale outside the human body through advanced DNA recombination technology.

Escherichia coli is often used as a host cell for producing genetically engineered interferon. The interferon sequence was accurately located near the lactose promoter of Escherichia coli, which improved the expression efficiency by more than 1000 times.

In order to realize the efficient expression of foreign genes, the culture technology of engineering bacteria is also very important.
