g-Trap Ni IDA瓊脂糖快速流動(dòng)色譜柱可直接用于基于固定金屬離子親和色譜（IMAC）的蛋白質(zhì)純化。

IMAC基于過渡金屬陽離子如Ni2+、Co2+與蛋白質(zhì)殘基組氨酸、半胱氨酸以及某種程度上色氨酸的相互作用。在G-Trap Ni IDA瓊脂糖快速流中，Ni2+使用與樹脂共價(jià)結(jié)合的亞氨基二乙酸基團(tuán)（IDA）固定在交聯(lián)的6%瓊脂糖上。 

g-Trap Ni IDA瓊脂糖快速流專為純化融合了6x組氨酸（6XHis）標(biāo)簽的重組蛋白而設(shè)計(jì)。

其他G-Trap IDA瓊脂糖快速流動(dòng)色譜柱提供1 ml和5 ml柱體積g-Trap Co IDA瓊脂糖快速流動(dòng)。人們可以根據(jù)需要在合適柱之間進(jìn)行選擇。
