Abstract
(a) 피브리노겐을 함유하는 용액에 포함된 피브리노겐을 1.5 ~ 2.5M의 글리신 농도가 되도록 글리신을 첨가하여 침전시킨 다음, 상등액을 제거하고, 침전물을 수득하는 단계(1차 글리신 침전(1st glycine precipitation));
(b) 상기 (a) 단계의 1차 글리신 침전 침전물을 용해 버퍼에 용해화하여 용해액을 수득하고, 상기 용해액을 0.2 ~ 1.2M의 글리신 농도가 되도록 글리신을 첨가하여 침전시키고, 상등액(supernatant)을 회수하는 단계(2차 글리신 침전(2nd glycine precipitation));
(c) 상기 (b) 단계의 상등액을 1.5 ~ 2.5M의 글리신 농도가 되도록 글리신을 첨가하여 침전시키고 침전물을 수득하는 단계(3차 글리신 침전(3rd glycine precipitation)); 및
(d) 상기 (c) 단계의 침전물을 용해 버퍼에 용해화하여 용해액을 수득하고, 이를 나노필터로 나노여과(nanofiltration, NF)하는 단계;
를 포함하는 피브리노겐의 정제방법에 관한 것이다.
본 발명에 따른 피브리노겐 단백질의 새로운 정제방법은 병원성 동물 유래 성분(바이러스)의 유입이 원천적으로 차단되어 안전성이 우수한 방법이며, 간단한 공정으로 회수율이 높은 고순도의 피브리노겐 단백질을 정제할 수 있으므로 매우 경제적이고 효율적일 뿐 아니라, 기존의 방법으로 정제된 피브리노겐에 비해 순도가 높아 국소작용력이 증가하는 장점이 있어, 혈액 관련 질환, 특히 혈액응고 질환 예방 및 치료에 유용하게 사용될 수 있다.
