Recombinant Protein Production in Medicine
Captions available
The idea
Recombinant DNA technology lets bacterial or animal hosts mass-produce a human protein, such as insulin, by expressing a cloned human gene.
In practice
A bacterial host carrying the cloned human insulin gene produces human insulin directly, where earlier treatment relied on insulin purified from pig and cow pancreases.
Where people slip
Recombinant insulin is human insulin produced in a bacterial host, not an artificial or animal-derived substitute.
