A variety of specialized cell culture vessels and impellers is available, including an optional packed-bed basket for applications requiring high yields of secreted products. The CelliGen 310 cell culture vessels are available in four sizes, ranging from 2.2 to 14.0 l total volume, and when used with the packed-bed basket, require 50500 g of FibraCel disks per run.
FibraCel offers the added benefit of sustaining long-term periods of high-density growth in perfusion. There is never any danger of clogging. Higher cell densities and productivities coupled with easier downstream processing also lower overall production costs. Elimination of cell filtration (including spin filters), lowers costs still further. Cells immobilized in the matrix serve as a renewable catalyst for continuous production of proteins. Fresh medium is fed into the bioreactor, washing secreted products through the matrix to provide a cell-free effluent.
