The mammalian cell expression system, known for its intricate glycosylation processes, is essential for achieving precise post-translational modifications and correct protein folding. Particularly crucial for downstream applications, transient expression in mammalian cells is widely utilized in the development and production of recombinant protein drugs, notably therapeutic recombinant monoclonal antibodies.


Gene Universal's mammalian expression services streamline the production and delivery of high-quality proteins and recombinant antibodies (rAbs), ranging from microgram to gram quantities, in CHO or HEK293 cells. With guaranteed protein quantity and purity, we leverage proprietary transient mammalian expression technology to optimize cellular pathways, resulting in exceptional protein and antibody yields (up to 3 g/L).


Our guaranteed mammalian protein expression packages encompass gene synthesis and subcloning, progressing seamlessly through protein expression and purification using our proprietary mammalian protein expression and purification technologies. Trust Gene Universal to propel your research forward with reliable and efficient mammalian protein expression solutions.
