The use of hollow fibre systems for bioproduction applications is nothing new and FiberCell Systems Inc. has been serving the R&D market since the beginning of this century. The FiberCell Systems high-flux polysulfone fibre cartridges offer the latest technology for best possible performance. Many different types of cells can be cultured in a hollow fibre bioreactor, both anchorage-dependent and suspension cells. In a medium sized (20ml) FiberCell cartridge it’s possible to culture up to 1.5 x 10^9 cells and in terms of bioproduction, easily outperform 20 x roller bottles, controlling cell mass simultaneously with the simple routine procedure for product harvesting. Use a hollow fibre bioreactor to produce mAbs, proteins, exosomes, virus, or to expand cells of various kinds of cells or to generate conditioned media.
