치료용 항체의 체외 기능 검증을 지원하기 위해, 저희는 ADCC 및 ADCP 분석용 리포터 세포주 시리즈를 개발하였습니다. 이 공학적으로 제작된 Jurkat 리포터 세포주는 표면에 Fcγ 수용체를 발현하며, 동시에 NFAT 반응 요소를 통해 루시퍼레이스 발현을 유도합니다. 표적 세포와 항체를 함께 배양하면, 항체 결합이 Fcγ 수용체의 클러스터링과 세포 내 신호 전달을 유도하고, 그 결과 NFAT 매개 루시퍼레이스 발현이 활성화됩니다.
ADCC response to anti-human CD20 antibody (RLU). Anti-human CD20 antibody-induced ADCC activity was evaluated using Human CD16a (158V) (Luc) Jurkat Reporter Cell (Cat.No. SCJUR-STF067) in the presence of Raji cells that express CD20 endogenously. The EC50 of anti-human CD20 antibody was approximately 0.0028 μg/mL.
