초록 | In animal cell culture, temperature is one of the key parameters which influence cell growth and recombinant protein production. Generally, most of mammalian cell cultures are performed at 37℃ which is normal human body temperature. In this study, to evaluate the effect of temperature on recombinant antibody production, rCHO cells were cultivated at various culture temperatures (33℃, 37℃ and 39℃). When the temperatures were lower than 37℃, cell growth was suppressed, but cell viability maintained at for longer culture periods. When the temperature was lowered from 37℃ to 33℃, the specific productivity was three times higher compared to the control. In contrast, when the temperature was heighten from 37℃ to 39℃, the specific growth rate was increased. Interestingly, when temperature was shifted instantaneously from 37℃ to 4℃ for 5 minutes, significant of increase glucose consumption was observed, which reveals dramatic changes in cellular metabolic activities driven by cold culture environments. |
