  • Hollow fiber immobilization with chopped microporous hollow fibers
    Patent number: 5510257
    Abstract: Most of the problems of prior art techniques for growing cells in hollow fiber devices can be avoided by growing the cells in short lengths (e.g., two inches (5.0 cm.) or less) of microporous hollow fibers. The fibers are prepared by chopping commercial lengths of hollow fibers into small pieces, preferably two inches (5 cm.) or smaller. Such chopped hollow fibers or bundles of hollow fibers are then added to a suitable medium for growth of cells and the medium is incubated. Very high cell densities have been observed in the chopped fibers.
