Abstract
Description
도면은 4개의 올리고뉴클레오티드의 어닐링을 나타낸다. 이들은 단일가닥이며 상보적 말단에 의해 어닐링될 수 있다. 갭은 교정 활성을 나타내는 폴리머라아제(예를들면, Pfx 폴리머라아제)로 채워진다.
도. 2: 4개 유전자 블롭의 어닐링의 개략도
vif 유전자는 vpr 단편과 중복서열을 나타내며, vpu 코딩단편은 rev 유전자(회색)와 중복서열을 나타낸다. PCR 단편은 변성되며 중복되는 상보적 말단은 잡종형성한다. 생성된 갭은 Pfx 폴리머라아제를 사용하여 채워진다. vif-vpr 단편은 vpu-rev 단편의 중복서열에 융합되며, 이것은 다시 융합에 사용된다.
도. 3: 외래 유전자를 MVA 게놈내로 삽입하기 위한 재조합 벡터에서 본 발명에 따른 융합 단백질을 코딩하는 서열의 클로닝 수법
융합된 vif, vpr, vpu 및 rev 폴리프로테인 코딩 영역은 Clal Apal 제한 부위를 포함하는 프라이머를 사용하여 증폭된다. 고 pCR 생성물은 수두 바이러스 ATI 프로모터를 함유하는 Clal/Apal로 절단된 벡터 pBNX65에 클론화된다. Tat 코딩 영역은 Acc651 제한부위를 함유하는 프라이머를 사용한 PCR에 의해 증폭되고 Acc651에 의해 선형으로 된 pBNX65 + vif-rev에 결찰된다. 생성된 발현 카세트(ATI 프로모터 + 본 발명에 따른 융합 단백질을 코딩하는 서열)은 Pacl 제한효소에 의해 분리되어 MVA 게놈 I4L 유전자내 영역(pBNX39)에 외래 유전자를 삽입하기 위한 재조합 벡터내로 삽입된다. pBNX39는 MVA 게놈(F1 I4L 및 F2 I4L)의 삽입부위의 측면 서열에 상동인 서열을 함유한다. MVA 게놈 및 pBNX39의 상동 재조합 후, 재조합 바이러스를 선별하기 위하여 벡터는 대장균 gpt 유전자(포스포리보실트랜스퍼라아제 유전자)를 함유한다. 재조합 바이러스의 정제 후, 선별 카세트는 Flank 1 및 Flank 1의 반복 서열(F1rpt)간의 상동 재조합에 의해 결실된다.
도. 4: MVA 게놈의 개략도
MVA는 Hind III를 사용한 제한처리 후 특징적인 단편(A-O)을 나타내는 선형 게놈을 함유한다. I4L 및 I5L 유전자간의 비 기능적 영역은 I 단편에 위치한다. pBNX39를 사용한 외래 유전자의 삽입은 56767-56768 위치에서 발생한다.
