Abstract

Centrifugal elutriation was used to produce cell cycle enrichedfractions of four commercially relevant recombinant cell lines,chosen to allow for variation in properties due to construct,expression system and parent cell type, from normally growingheterogeneous batch cultures. As these fractions had identicalculture histories and had not been subjected to any insult orstress which was likely to have adversely affected cellularmetabolism, they were ideal for further study of cellularproperties. Specific productivity, cell size and cell cyclestate of replicate elutriated fractions were measured for eachcell line. Results showed that cell size was the major cellulardeterminant of productivity for all cell lines examined. Productformation was not restricted to any particular cell cycle phaseand in all cases, production occurred irrespective of cell cyclephase. Specific productivity was lowest when the majority ofcells in the fraction were G(1), intermediate when themajority of cells in the fraction were S phase and greater whenthe majority of cells in the fraction were in G(2)/M. However, the evidence suggests that size is the major cellulardeterminant of productivity; the apparent relationship betweencell cycle and productivity is secondary and can simply beascribed to the increasing size of cells as they progress thoughthe cell cycle. Thus, in addition to cell density and viabilitycell size is the cellular parameter which should be incorporatednot only into mathematical models of recombinant mammalian cellproduction processes but also into process monitoring andcontrol strategies.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
