Abstract
본 발명에 따르면, AAV1~AAV5 벡터 표준품의 생산 효율성이 향상되고, 오염된 다른 물질들에 기인하는 부적격 반응을 최소화할 수 있는 정제과정이 향상되었으므로, 특히 임상시험용의약품 유전자 치료제의 품질관리를 하는데 사용 가능하고 유용하다.
Description
도 2는 본 발명에 따른 AAV 혈청형 벡터의 생산조건으로 생산된 AAV 2 혈청형 벡터를 CsCl 밀도구배 원심분리 방법 또는 이온교환수지 크로마토그래피 방법과 CsCl 밀도구배 원심분리방법을 함께 사용한 방법으로 정제한 결과를 나타낸 것이다.
도 3은 도 2의 결과를 AAV 2 혈청형에 대한 특이적 다클론 항체를 이용하여 웨스턴블러팅한 결과를 나타낸 것이다.
