Description_x000D_ General description_x000D_ Ideal for MAb and cellular protein production. Viable in vitro alternative to using mouse ascites. Bioreactors will utilize innovative membrane technology to separate the cell cultivation area from the media chamber. Cell and cellular-secreted product with a MWCO of 10 kDa are retained between two non-cytotoxic membranes. The upper semi-permeable membrane allows continuous nutrient diffusion and waste elimination. The lower membrane provides direct oxygenation and ensures optimum gas exchange.
