The present invention relates to a method of preparing an immobilised metal ion affinity chromatography (IMAC) adsorbent, which comprises to provide chromatography ligands comprised of alkylene diamine triacetic acid, or a derivative thereof, and coupling thereof to a carrier via nitrogen. In an advantageous embodiment, the alkylene diamine triacetic acid is ethylene diaminetriacetic acid (ED3A).
本发明涉及一种制备固定金属离子亲和色谱(IMAC)吸附剂的方法,包括提供由烷基二胺三乙酸或其衍生物组成的色谱配体,并通过氮原子将其偶联到载体上。在一个有利的实施例中,烷基二胺三乙酸是乙二胺三乙酸(ED3A)。
