Scale up on the MaxCyte STX Requires No Re-optimization


CHO-S cells were transfected with an IgG expression plasmid via small- or large-scale electroporation using the MaxCyte STX. Antibody titers >1.2 grams/L were detected within two weeks of transient transfection for both transfections. A total of 3.4 grams of antibody was produced from a 2.8 L culture following a single transfection.
