描述

一般說明

HybridSPE-Phospholipid磷脂去除技术是一种简单且通用的样本制备平台，设计用于在 LC-MS 或 LC-MS/MS 分析之前，从生物血浆和血清中总体去除内源性蛋白和磷脂干扰。首先通过加入和混合酸化乙腈使生物血浆或血清发生蛋白沉淀。然后通过离心除去沉淀蛋白，并将所得上清液上样至 HybridSPE-Phospholipid 96 孔板或固相萃取柱上，其作为化学过滤器，专门靶向去除内源性样品磷脂。截留磷脂的原理是HybridSPE-Phospholipid固定相键合的专有氧化锆离子和所有磷脂都具有的磷酸根发生高度选择性的路易斯酸碱相互作用。得到的洗脱液可立即用于 LC-MS 或 LC-MS-MS 分析。

HybridSPE-Phospholipid 96 孔板和Ultra固相萃取柱有“孔内”/“柱内”沉淀法可供选择。即先将生物血浆/血清加入孔内或柱内，接着加入酸化乙腈（沉淀剂）。短暂混合/涡旋后，抽真空。96孔板和 Ultra固相萃取柱含有一系列低孔隙率疏水滤膜/筛板，这些填充柱床的滤膜/筛板组件作为深层过滤器，有助于在提取过程中同时去除磷脂和沉淀蛋白。标准 HybridSPE-Phospholipid磷脂固相萃取小柱需要采用“离柱”沉淀法。
