Mammalian and insect cell lines are used com. to produce products for both the human and animal health markets.Due to regulatory issues surrounding the use of animal-derived raw materials in culture media, JRH Biosciences has developed four regulation-friendly media formulated using raw materials that are recombinant, synthetic or non-animal-derived.Cells can be transferred directly from serum-containing cultures into these media without extensive adaptation or extended lag phases.EX-CELLVero SF supports the growth of Vero cells in stationary flasks as well as on microcarriers.EX-CELL293-S supports the growth of 293 cells as single cells in suspension cultures.EX-CELL302 was designed for the culture of CHO cells in suspension systems.In each of these media, cells achieve doubling times and final cell densities comparable to 10% FBS controls.EX-CELL420 was optimized for growth of Sf9 and Sf21 insect cell lines, supporting cell densities of >107 cells/mL (viability >95%) for more than 10 days.
