Challenge:
A client experienced low protein yield in CHO-based production, limiting their ability to generate sufficient material for preclinical studies and increasing overall manufacturing costs.
Approach:
Profacgen developed customized basal and feed media formulations tailored to the client's specific cell line and protein. Nutrient optimization was guided by metabolic profiling to identify and address consumption patterns and limiting components. Process conditions including feeding schedules and culture parameters were refined to maximize productivity while maintaining cell health.
Outcome:
Achieved a 2–3× increase in protein expression compared to standard media formulations. Cell viability was significantly improved throughout culture duration, and process consistency was enhanced across multiple batches, enabling reliable production for downstream applications and scale-up.
Challenge:
A client faced low transfection efficiency and inconsistent expression levels during HEK293 transient transfection, resulting in unreliable yields and delayed project timelines.
Approach:
Profacgen developed an optimized serum-free medium specifically formulated for HEK293 transient transfection applications. Strategic addition of proprietary supplements and anti-agglomeration agents minimized cell clumping and enhanced DNA uptake efficiency. Transfection conditions including DNA-to-lipid ratios and cell density were systematically optimized.
Outcome:
Achieved a significant increase in transfection efficiency with consistent performance across batches. Higher protein yield enabled sufficient material for downstream studies. Reproducibility was markedly improved, allowing the client to confidently scale transient production for their research and early-stage development needs.
Challenge:
A client encountered unexpected variability in production performance across batches, with inconsistent cell growth and protein yield that could not be explained by their standard process controls.
Approach:
Profacgen conducted comprehensive QC testing on incoming media components, analyzing vitamin concentrations, amino acid profiles, and endotoxin levels. Raw material variability was identified as the root cause, with specific lots showing deviations from specifications that impacted cell performance.
Outcome:
Root cause was successfully identified and resolved through updated raw material qualification procedures. Process consistency was restored, with subsequent batches meeting all performance specifications. Product quality improved as a result of stable culture conditions, enabling the client to resume reliable production.
