Recombinant proteins are widely used to study various pathophysiological processes. Nevertheless, the establishment of the desired protein-producing stable mammalian cell lines using traditional methods is hampered by multiple laborious steps. In this chapter, we describe a simple and robust system that allows for the derivation of stable transgenic cell lines in 293 cells, yielding high protein expression levels, in a short time period. This methodology is based on the piggyBac transposon system and, notably, it allows for inducible production of the protein of interest. Moreover, it can easily be used in conventional laboratory cell culture settings and does not require any specialized devices. Herein, we outline all the steps of this procedure in detail and point out specific considerations.
