Dj. Distefano et al., FEEDING OF NUTRIENTS DELAYS APOPTOTIC DEATH IN FED-BATCH CULTURES OF RECOMBINANT NS0 MYELOMA CELLS, Biotechnology letters, 18(9), 1996, pp. 1067-1072
The addition of concentrated nutrient solutions in fed-batch cultures
of recombinant GS-NSO cells delays the onset of apoptosis by 24 to 48
hours and decreases the specific rate of apoptotic death approximately
two-fold. This decrease in apoptosis appears primarily responsible fo
r the increase in culture longevity that results in five- to ten-fold
increases in final product concentrations in fed-batch cultures.
