Continuous Harvesting Of Extra-Cellular Proteins From Mammalian Cell Cultures Utilizing Small-Scale Perfusion
The use of a small-scale cell culture system not only maximizes the production of valuable protein but also avoids the high capital cost associated with system scale-up. Continuous harvesting can provide significant improvements in protein yields when compared to those of typical batch operations.

Microbial Fermentation In Single-Use Xcellerex™ XDR-50 MO Fermentor SystemThis application note describes the performance of a single-use Xcellerex XDR-50 bioreactor system when used in cultivations of E. coli and of modified Pseudomonas fluorecsens (P. fluorescens) producing a monoclonal antibody (MAb). Both the achieved microbe densities and product yield were shown to be consistent with the performance of conventional stainless steel systems.
