4Cell HEK293 Media

The 4Cell^® HEK293 media portfolio addresses the complex requirements of human embryonic kidney cell cultivation across diverse gene therapy applications. These chemically defined, serum-free formulations support adeno-associated virus (AAV) production, lentiviral vector manufacturing, and recombinant protein expression while maintaining consistent performance at commercial scale.

Each medium variant targets specific process requirements: HEK TF optimizes transient transfection efficiency, HEK ViP formulations enhance viral vector production with specialized nutritional profiles, HEK GM delivers robust growth for stable cell lines, and HEK FS_2 provides concentrated feeding solutions for extended cultivation periods. The hydrolysate-free composition ensures regulatory compliance while supporting high cell densities exceeding 4E6 cells/mL in both shake flask and bioreactor systems.

Key technical specifications include 6-8 mM L-glutamine supplementation requirement, pH range of 7.0-7.5, and osmolality targets of 290-300 mOsmol/kg. The media support standard cultivation conditions at 37°C with 5% CO2 atmosphere. Compatible with polycationic transfection reagents including PEI-based systems, these formulations achieve transfection efficiencies exceeding 80% in optimized protocols.

Available in liquid and powder formats from 1 L bottles to 500 L containers, the portfolio accommodates research through manufacturing scales. Quality assurance includes ISO 9001 and ISO 13485 manufacturing standards with lot-specific certificates of analysis. The animal component-free design reduces regulatory burden while maintaining the nutritional complexity required for demanding viral vector and protein production processes.
