초록

형질전환된 담배세포 배양을 이용한 hGM-CSF 생산에 있어 polyurethane foam 내 고정화법을 이용하여 연속배양의 가능성을 확인하였고 spinner flask에서의 배양에 따른 영향을 알아보았다. 16일 동안 3번의 배지교환에도 세포의 활성이 유지되어 hGM-CSF 생산량은 계속적으로 증가하였다. 온도와 교반속도를 동일하게 하였을 때 spinner flask에서의 hGM-CSF 생산량은 17.3 ${\mu}g/L$으로 100-mL flask의 9.8 ${\mu}g/L$보다 증가하였다. 따라서 최적의 배지교환 속도와 양을 결정하여 spinner flask에서 연속배양을 실시할 경우 세포 재사용이라는 경쟁력과 함께 높은 hGM-CSF 생산량이 얻어질 것으로 예상된다.

Effect of immobilization on the production of human granulocyte-macrophage colony-stimulating factor (hGM-CSF) by Nicotiana tabacum cells was investigated using polyurethane foam as immobilization matrices. The cell activity and the hGM-CSF production were maintained for 16 days in spite of 3 times of media exchange. Under the same conditions of temperature and agitation rate, maximum concentrations of hGM-CSF in a 500-mL spinner flask and 100-mL Erleuneyer flasks were 17.3 ${\mu}g/L$ and 9.8 ${\mu}g/L$, respectively. Consequently high hGM-CSF production could be possible in spinner flask when the rate and amount of media exchange were optimized.
