Reliable small-scale HTP antibody expression

When your research focuses on discovery and early development of a therapeutic antibody, having reliable, high quality proteins from the start can reduce the risk of late-stage failures. Our semi-automated, high-throughput platform enables reproducible and rapid production of antibodies from transiently transfected mammalian cells, while remaining flexible enough to address the needs of the rapidly evolving immunotherapy field.

As with our mid- and large-scale protein expression services, high yields are achieved with a combination of outstanding sequence optimization and high-efficiency Gibco ExpiCHO or Expi293 expression systems.

Antibody expression and recovery consistency

To prevent false negatives due to poor yield, it is important to utilize a platform that maximizes expression consistently within and between production runs. Figure 1 demonstrates reproducible expression and recovery of antibodies across independent runs.

Two graphs show protein concentration for 38 antibodies expressed in ExpiCHO (left panel) and Expi293 (right panel) correlate well between independent production runs, demonstrating good R2 and P values.

To further prevent candidate dropout later in development, expression levels should be consistent as you scale up to larger cultures. Figure 2 demonstrates consistent relative expression between small-scale, high-throughput cultures (2.5 mL) and either 200 mL or 1 L cultures.

Two graphs show protein titer from supernatant after 10 days expression in Expi293 (left panel) and ExpiCHO (right panel) correlate well between 2.5 mL and 200 mL or 1 L cultures, demonstrating good R2 values.
