waters 肽分析離子交換色譜柱

離子交換色譜

離子交換色譜基于電荷差異進(jìn)行肽分離，與傳統(tǒng)的反相色譜相比，更適合需要不同/正交分離機(jī)制的分析。

通常情況下，采用鹽濃度不斷增加的梯度進(jìn)行分離，體積較小且所帶電荷較少的肽會(huì)在較長的肽片段之前洗脫。與反相肽分離不同，洗脫液的pH會(huì)顯著影響分離，因此需要進(jìn)行方法開發(fā)以獲得滿意的色譜結(jié)果。

waters 肽分析離子交換色譜柱與其它生物分離一樣，相比基于HPLC的色譜柱，使用粒徑更小的UPLC/UHPLC色譜柱可以在更短的時(shí)間內(nèi)實(shí)現(xiàn)優(yōu)異的組分分離度。

Protein-Pak HR離子交換玻璃色譜柱

Protein-Pak HR填料基于具有1000 ?大孔徑的剛性、親水性聚甲基丙烯酸酯顆粒。這種天然的親水性聚合物可減少非特異性吸附，從而實(shí)現(xiàn)蛋白質(zhì)質(zhì)量和生物活性的定量回收。這些填料可兼容pH 2～12的緩沖液，而且能夠耐受腐蝕性溶液。

Protein-Pak HR離子交換劑可提供：

Q官能團(tuán)，強(qiáng)陰離子交換劑
DEAE，弱陰離子交換劑
SP，強(qiáng)陽離子交換劑
CM，弱陽離子交換劑

Protein-Pak HR 8 μm和15 μm填料可預(yù)填充于沃特世高級(jí)純化(AP)玻璃色譜柱中。這些色譜柱與多種分析型及制備型LC儀器兼容。

BioSuite離子交換HPLC色譜柱

BioSuite離子交換色譜柱包括四種分離填料 - SP強(qiáng)陽離子交換劑和CM弱陽離子交換劑，以及Q強(qiáng)陰離子交換劑和DEAE弱陰離子交換劑 - 這些填料都與pH穩(wěn)定（pH 2～12）的甲基丙烯酸酯類聚合物樹脂鍵合。廣泛的分離填料選擇為色譜工作者提供了靈活性，使其能夠開發(fā)出基于微小電荷差異分離蛋白質(zhì)或肽的方法。部分BioSuite離子交換色譜柱還附帶PEEK硬件，此外，還提供用于實(shí)驗(yàn)室級(jí)制備型應(yīng)用的21.5 mm內(nèi)徑色譜柱
