Wired Faculty App

What are recombinant proteins ? How do bioreactors help in their production ?

Solution

Recombinant protein is the protein formed when any protein encoding gene is expressed in a heterologeous host.

Bioreactors can be used to harbour cloned genes of interest and the cultures can be used for extracting the desired recombinant protein. Bioreactors help in the large scale productionand provide optimal conditions for achieving the desired recombinant protein by biological methods.
