At the research scale, transient protein expression platforms offer protein production labs many advantages over a stable system. However, this wasn’t always the case. Stable production used to be the only way to produce meaningful amounts of protein in a relatively short time period until in 2012 when Gibco launched Expi293 Expression System.
At the platform’s debut, the Expi293 transient expression platform offered up to 6x higher yield than previous transient systems and enabled protein harvest in as little as one week, which was weeks if not months faster than that achievable via stable development. Thermo Fisher Scientific has since continued to innovate upon the “Expi” platforms and launched ExpiCHO Expression System in 2015 and ExpiSf Expression System in 2018. For researchers and facilities needing to rapidly produce high amounts of protein, the Expi protein expression systems offer integrated solutions with yield, speed, and cost benefits.
In addition to the obvious yield benefits offered by Expi platforms, labs can help minimize the burden on their staff by reducing hands-on-time needed for protein production, freeing up researchers to perform more experiments and analysis.
Stable cell line production can take almost a month; with Expi systems you can obtain sufficient yield to transiently express protein in as few as 5 days.
For researchers who need as much protein as possible, we've developed protocols that maximize yields without adding a significant time investment.
Since Expi systems offer high-yield and rapid expression, scientists can save on their cost/mg of protein (based on decreased plastics use, reduced staff time, and reduced DNA).

While insect cells perform most of the post-translational modifications that occurs in mammalian cells, N-glycosylation in insect cells results in only simple glycan moieties as opposed to complex glycans that occur in mammalian cells, such as those in the Expi293 Expression System. For structural analysis where simple protein glycosylation is favorable, ExpiSf Expression System can be an alternative, low-cost platform for these applications.
