High MWCO (20kd@50%) hydrophilic fiber for trapping larger molecules, hybridoma and lymphocyte cultures. 20kd MWCO allows TGF beta and TNF alpha to diffuse away while retaining antibodies. Can support up to 1011 cells and produce 75-150mg of monoclonal antibody every two days. Also used for large-scale adenovirus production at levels of 1-5 x 1013 pfu (plaque forming units).
