Tailoring success with diverse protein expression systems
The choice of the cell system plays a crucial role in determining the success of your project.
Our Protein Expression Technology empowers the successful expression of membrane proteins in a variety of cell systems, including bacteria, yeast, insect cells, and mammalian cells.
Bacteria: powerhouse of prokaryotic expression
E. coli, a prokaryotic expression system, offers rapid and cost-effective protein production. It facilitates high yields, ideally for smaller proteins, especially those not requiring complex post-translational modifications.
Yeast: balancing simplicity and complexity
Yeast systems, including Saccharomyces cerevisiae, offer eukaryotic advantages, facilitating the expression of glycosylated proteins crucial for certain applications. This system strikes a balance between simplicity and post-translational modifications. Eurofins CALIXAR leverages this system for its adaptability to membrane proteins, ensuring native functionality.
Insect cells: mimicking complexity
Employed in baculovirus expression systems, the Sf9 insect cell expression system mimics eukaryotic complexity, offering a more native environment for membrane protein expression. It proves beneficial for complex proteins requiring intricate folding and post-translational modifications. Our expertise in this system ensures reliable expression and functionality.
Mammalian expression: precision and versatility
Human Embryonic Kidney (HEK) cells, a eukaryotic system, closely emulate the human cellular environment, and also offer precision and versatility. Ideal for expressing human membrane proteins, CALIXAR utilizes HEK cells to achieve precise folding and post-translational modifications, producing native and functional targets.
Chinese Hamster Ovary (CHO) cells, another eukaryotic system, excel in producing complex proteins with accurate glycosylation patterns. CALIXAR harnesses the precision of CHO cells to express membrane proteins, ensuring the production of native and functional targets.
