Abstract
Description
도 2는 현탁액 모드에서 세포를 팽창하고, iCELLis Nano™ 브랜드 접착-배양 생물반응기에 현탁액-적응 세포를 접종하고 이후에 접착성 모드에서 세포를 성장시킨 후, iCELLis Nano™ 브랜드 접착-배양 생물반응기를 사용한 우리 공정의 전형적인 결과를 나타준다. a) HEK293 세포 성장 곡선, b) 293T 세포 성장 곡선. 포도당 소비와 젖산 축적은 세포 성장과 관련있다.
도 3은 AAV2 발현 녹색 형광 단백질(GFP)의 제조를 위한 칼슘 포스페이트 형질감염 이후 24 시간 후 293T 세포의 형광 현미경 사진이다. 293T 세포는 현탁액에서 팽창되고,iCELLis Nano™ 브랜드 4m2 생물반응기에 접종하고 AAV 발현 중 접착성 모드로 성장된다.
도 4. 수확된 아데노바이러스 물질의 DNA 제거를 위한 상이한 벤조나제 농도와 접종 시간의 효과 테스트.
도 5. 다양한 바이러스 수확 샘플을 위한 혼탁도 대 시간.
