IX 因子 (FIX) 是一种维生素 K 依赖性血浆蛋白,是止血和凝血的关键调节因子。 FIX 内的突变可能导致潜在的致命疾病,例如 B 型血友病和静脉血栓栓塞 [1, 2]。 FIX 相关疾病的新疗法的开发需要能够轻松纯化 FIX 的技术,以便研究该蛋白质的多种相互作用。重要的是,该技术应该适用于从非人类来源分离 FIX,以便可以在动物身上测试潜在的新疗法。为此,我们研究了专为人类 FIX 亲和纯化而设计的 GE IXSelect 柱在从小鼠血浆中纯化小鼠 FIX 的能力方面的适用性。使用该色谱柱,我们从 100 mL 小鼠血浆中分离出 80 μg 小鼠 FIX。这一结果不仅证明了 IXSelect 在纯化 FIX 同系物中的新用途,而且表明小鼠和人类 FIX 之间存在与 IXSelect 结合配体相互作用的保守结构。
Factor IX (FIX) is a vitamin K-dependent plasma protein that functions as a key regulator in hemostasis and blood clotting. Mutations within FIX can cause potentially fatal conditions such as hemophilia B and venous thromboembolism [1, 2]. The development of new treatments for FIX-associated diseases requires technology that enables FIX to be easily purified, in order to study the protein's diverse set of interactions. Importantly, the technology should be applicable to the isolation of FIX from non-human sources, so that potential new therapies could be tested in animals. To that end, we investigated the applicability of the GE IXSelect Column, designed specifically for affinity purification of human FIX, in its ability to purify mouse FIX from mouse plasma. With this column, we isolated 80 μg of mouse FIX from 100 mL of mouse plasma. This result demonstrates not only a novel use for IXSelect in the purification of a FIX homolog, but also suggests the existence of a structure conserved between mouse and human FIX that interacts with the IXSelect binding ligand.
