Lonza Transfection Technology for Protein Production
The demand for recombinant protein production is growing constantly. Protein amounts in the high microgram to kilogram range are needed for numerous applications like protein characterization, functional studies, cell-free screening, proteomics, pre-clinical and clinical approaches. Due to their capacity for proper protein folding, assembly and post-translational modification mammalian and insect cell expression systems have gained further relevance.
Lonza transfection technology now includes perfect tools for any protein production challenge. While Nucleofection® is the method of choice for generating stable clones or transient protein production in very sensitive cell lines, XpressNOW™ is optimized for suspension HEK293 cells and offers highly cost-efficient transfection for transient protein production.
XpressNOW™ transfection reagent gets you functional protein from suspension HEK293 cells within days, regardless of culture scale or format.
The Nucleofector® Technology is the ideal tool for gene transfer into even difficult-to-transfect mammalian and insect cells. It has been successfully used for both
Efficient gene transfer for cell lines most relevant for protein production. Cells were transfected by Nucleofection® with pmaxGFP™. 24 hours post Nucleofection® maxGFP® positive cells were determined by FACS analysis (light bars). Viabilities were assessed after propidium iodide staining by FACS analysis (dark bars).
