Abstract
Description
또한, 본원발명은 디올-잔기를 함유하는 수지를 포함하는 이중가닥 DNA 정제용 지지체의 제조방법에 관한 것이다. 상기 방법은 (a) 상기 수지의 디올 잔기를 나트륨 m-페리오데이트로 산화시킴에 의해 활성화시키고, 및 (b) 아스코브산의 존재하에 환원성 아민화에 의하여 올리고뉴클레오타이드를 지지체의 잔기에 커플링시키는 것으로 이루어진 단계를 포함한다. 바람직하게는, 상기 올리고뉴클레오타이드는 서열번호 28 및 서열번호 30의 서열로부터 선택되는 피리미딘-풍부 서열을 포함하고, 또한, 상기 올리고뉴클레오타이드는 이중가닥 DNA에 존재하는 뉴클레오타이드 서열과의 하이브리드화에 의해 비-정규 트라이애드(non-canonical triad)의 형성없이 이중가닥 DNA와 삼중나선을 형성할 수 있다.
