Recombinant protein expression technology enables study of gene regulation and protein structure and function. Utilization of recombinant protein expression can also vary widely—from investigation of function in vivo to large-scale production for biotherapeutic drug discovery and structural studies. Using the right protein expression system for your specific application is critical to success. Consider protein solubility, functionality, purification speed, and yield when choosing an expression system. We offer a wide selection of superior mammalian, insect, yeast, bacterial, algal, and cell-free protein expression systems to suit your research needs, backed by trusted brands like Gibco and Invitrogen.
