Achieve High Protein Yields in Suspension 293 Cells

Achieve High Protein Yields Using TransIT-PRO® Transfection Kit in Suspension 293 Cells. Ten different secreted (non‐antibody) proteins were transiently expressed in FreeStyle™ 293‐F cells (Life Technologies) using TransIT‐PRO (1.5:1) or 293fectin™ (Life Technologies, 2:1) transfection reagents according to manufacturer's protocol. Cells were grown in FreeStyle™ 293 Expression Medium at transfected at a density of 1 x 106 cells/ml. The scale of the transfection for each protein varied between 1‐6 L of culture.

High Levels of Antibody Expression at Different Volume Scales using TransIT-PRO® Transfection Kit

Antibody Expression Scale(L) Yield(mg/L)
Eight different antibodies were transiently expressed in FreeStyle™ 293‐F cells (Life Technologies) using the TransIT‐PRO Transfection Reagent (1:1) according to manufacturer’s instructions. Cells were grown in FreeStyle™ 293 Expression Medium and transfected at a density of 1 x 106 cells/ml.

The scale of the transfection for each protein varied between 1 ‐ 11 L of culture.
The protein yields range from 11.2‐ 33.3 mg/L.
