Large-Scale Protein Production

Large-Scale Protein Production

Large-scale recombinant protein production is becoming increasingly important for applications in the field of proteomics, structural biology and protein therapeutics. When large quantities of protein (from mg to g amounts) needs to be produced from either bacterial (e.g. Escherichia coli) or eukaryotic cell-based culture (e.g. yeast, insect and mammalian cell), cells must be cultured in large volume by the implementation of fermentation techniques. Fermentation can improve efficiency by increasing cell density and provide easy-to-handle large culture over 4 liters. Depending on the high cell density as well as fermentation strategy, we can optimize cell culture conditions to increase cell mass and finally improve recombinant protein yield.

Profacgen is fully equipped to meet this production demand for large quantities of pure and active protein. Our versatile protein expression platform is equipped with a comprehensive series of bioreactors (from fermenters to wave mixers), which can accommodate protein production projects at different scales, ranging from milligrams to hundreds of grams.
