Abstract
Description
도 2는 각각 하기 실시예 1 및 실시예 2의 펩티드 1(hG18-TT) 및 펩티드 2(hG21-TT)를 사용해 작제된 컨쥬게이트를 일회 투여하여 ELISA에 의해 측정시 토끼에서의 항체 반응을 에 따라 도시한다.
도 3은 면역원 G18-TT 및 G21-TT을 사용해 프로세싱된 마우스에서 인간 위 암 세포(BCG-823 세포)의 억제를 도시한다. 42일째 동물을 인간 위 암 세포를 함유하는 멸균된, 봉합, 중공사 세관을 사용해 이식시켰다. 도시된 바와 같이, 일부 동물은 면역원에 종래의 위 암 화학요법 약물이 더해져 투여되었다.
도 4는 G21 면역원을 사용해 수득한 결과와 비교하여, 본 발명의 상이한 면역원 컨쥬게이트를 사용해 면역화하여 마우스에 의해 수득된 결과를 도시한다.
