Abstract
Description
도 2는 본 발명의 일 실시예에 따른 3 단계의 클론 선택 과정에서 확인된 SNAP25의 절단 정도를 웨스턴 블랏팅 분석을 통해 확인한 결과를 나타낸 것으로, 2 단계의 클론 선택 과정(2nd clonal selection)에서 42번 클론을 포함하는 6개의 클론 중 유의미하게 BoNT/A에 의한 SNAP25의 절단 현상을 나타낸 42번 클론만을 선택하였고, 3 단계의 클론 선택 과정(3rd clonal selection)에서 24번 클론(42F)은 복수의 동일한 실험에서 일관되게 BoNT/A에 의한 SNAP25의 절단 현상을 나타낸다.
도 3은 본 발명의 일 실시예에 따른 N2-42F와 그의 부모 Neruo-2a 세포간의 분열시간(Doubling time)을 확인한 그래프를 나타낸 것이다.
도 4는 본 발명의 일 실시예에 따른 세포의 형태학적 확인을 위하여, 20배의 배율로 Leica DMi8을 사용하여 부모 세포인 Neruo-2a와, SiMa 세포 및 클론 N2-42F가 60%의 컨플루언스일 때 확인된 이미지를 나타낸 것이다.
도 5는 본 발명의 일 실시예에 따른 SiMa 세포 및 N2-42F에 다양한 농도의 BoNT/A를 처리하였을 때 나타나는 SNAP25의 절단 정도를 웨스턴 블랏팅 분석을 통해 확인한 결과를 나타낸 것이다.
도 6은 본 발명의 일 실시예에 따른 본 발명의 클론 선택 과정을 통해 얻어진 N2-42F의 계통 안정성을 웨스턴 블랏팅 분석을 통해 확인한 결과를 나타낸 것이다.
