Using nanoscale bioreactors to characterize sub-populations of CHO clones and screen transfected pools

Abstract
Traditional means to quantify growth and production rates for antibody-expressing CHO lines involve sampling aliquots and supernatants from well plates that have been seeded with single cells. The number of clones studied is often limited by cloning efficiencies (typically 5-50%) and the inability to handle large numbers of well plates. The speed at which each clone can be measured is limited by the growth rates of cells and the number of cells required to perform each assay. Both of these factors lead to a practical throughput of 100s of clones screened over the course of 2-4 weeks. Furthermore, each readout of a clone offers little to no insight into the behavior of sub-populations within each clone since the aliquot or supernatant is just a small sample representing the entire population.
