Patents in therapeutic recombinant protein production using mammalian cells.

The industrial production of recombinant proteins preferentially requires the generation of stable cell lines expressing proteins in a quick, relatively facile, and a reproducible manner. Different methods are used to insert exogenous DNA into the host cell, and choosing the appropriate producing cell is of paramount importance for the efficient production and quality of the recombinant protein. This review addresses the advances in recombinant protein production in mammalian cell lines, according to key patents from the last 30 years.
