项目摘要
An analytical method that uses two different high-performance liquid chromatography (HPLC) columns in tandem has been developed that separates three major selenium-containing proteins (albumin, glutathione peroxidase and selenoprotein P) found in human blood plasma. The first column was a heparin affinity column and the second was a gel filtration column whose outlet was directly connected to an inductively coupled plasma-mass spectrometry. The method successfully separated plasma selenium into the three selenium-containing proteins and revealed the preferential retention of selenium in the form of selenoprotein P in a selenium-deficient human and in selenium-deficient mice, and a preference for supplemented selenium to be taken up as selenoprotein P.Advantages of the tandem column method are that it allows rapid and convenient analyzes of the distribution of plasma selenium, and that it is suitable for stable isotope tracer studies and metal interaction studies.
已经开发了一种分析方法,该方法使用两种不同的高效液相色谱(HPLC)柱串联,可分离人血浆中发现的三种主要含硒蛋白(白蛋白、谷胱甘肽过氧化物酶和硒蛋白P)。第一个柱是肝素亲和柱,第二个柱是凝胶过滤柱,其出口直接连接到电感耦合等离子体质谱仪。该方法成功地将血浆硒分离成三种含硒蛋白,并揭示了硒在硒缺乏的人和硒缺乏的小鼠中以硒蛋白P的形式的优先保留,以及补充的硒以硒蛋白P的形式被吸收的优先选择。串联柱方法的优点是,它允许快速和方便地分析血浆硒的分布,并且它适合于稳定同位素示踪研究和金属相互作用研究。
