From Gene to Protein: Streamlining Mammalian Expression with Gene Universal

In the fast-evolving landscape of biologics development, the demand for high-quality recombinant proteins and monoclonal antibodies has never been higher. At the core of this innovation lies the mammalian cell expression system, a powerful platform known for its ability to deliver accurate post-translational modifications—especially glycosylation—and proper protein folding. These features are critical when developing therapeutic proteins and recombinant antibodies (rAbs), ensuring they meet the structural and functional requirements for downstream applications.

The Power of Mammalian Cell Expression Systems

Unlike prokaryotic or insect cell systems, mammalian cells such as CHO and HEK293 possess the complex cellular machinery necessary to replicate the glycosylation patterns found in human proteins. This capability is essential for the biological activity, stability, and safety of protein therapeutics, especially monoclonal antibodies. Among the various mammalian expression strategies, transient expression has emerged as a leading solution for rapid and scalable protein production.

Why Transient Mammalian Expression Matters

Transient transfection enables researchers to express recombinant proteins without generating stable cell lines, significantly reducing development timelines. It is particularly useful for early-stage drug discovery, candidate screening, and structure-function studies. Moreover, it provides the flexibility to produce milligram to gram-level quantities of target proteins quickly and cost-effectively.
