氟固相萃取辅助的生物分子质谱分析新方法

氟固相萃取(Fluorous solid-phase extraction,FSPE)是一种基于全氟化合物之间氟-氟相互作用的固相萃取技术,通过在目标分子上进行氟标签衍生,利用高氟化固相吸附剂实现特异性的分离纯化.这一技术在有机合成、催化,以及化学和生物分离分析等诸多领域应用广泛.近年来,由于氟固相萃取和生物质谱技术之间良好的兼容性,两者联用结合的分析方法受到了研究者的广泛关注.本文在简要介绍氟固相萃取技术原理的基础之上,重点综述了其在生物质谱分析领域中的应用,并对其发展前景进行了展望.

Fluorous Solid-Phase Extraction Assisted New Methods for Analysis of Biomolecules with Mass Spectrometry

Fluorous solid-phase extraction ( FSPE ) is a solid-phase extraction technique based on fluorous affinity between perfluorous compounds. It requires derivatization on analytes with fluorous tags and further specific separation accomplished by perfluorinated solid phase. This technique has extended to various research fields with broad application including organic synthesize, catalysis, chemical and biological analysis. Recently, owing to its good compatibility with mass spectrometry, new analytic techniques relying on FSPE coupled to biological mass spectrometry have received wide attention. This review briefly introduced the principle of FSPE and emphasized on its application for the analysis of biomolecules with mass spectrometry, as well as its outlook of future development.
