Protein-Free Human-Human Hybridoma Cultures in an Intercalated-Spiral Alternate-Dead-Ended Hollow-Fiber Bioreactor
Batch cell cultures of a human-human hybridoma line in a convective flow dominant intercalated-spiral alternate-dead-ended hollow fiber are compared with those using conventional axial-flow hollow fiber bioreactors and a stirred-tank bioreactor. Relatively short-term fed-batch and perfusion cell cultures were also employed for the intercalated-spiral bioreactor. When operating conditions of a batch intercalated-spiral bioreactor were properly chosen, the cell growth and substrate consumption paralleled that of a batch stirred-tank culture. The results verified the premise of the intercalated-spiral hollow fiber bioreactor that nutrient transport limitations can be eliminated when the convective flux through the extracapillary space is sufficiently high.
