Flow field-flow fractionation (FlFFF) is a separation method capable of size-sorting particles and biological macromolecules like proteins, DNA, cells, and etc. in an empty channel space without packing materials. During separation of macromolecules by FlFFF, eluting fractions of narrow size range can be collected and utilized for further biological analysis. In this presentation, recent efforts to incorporate mass spectrometry (MS) with FlFFF either by off-line or on-line will be described with applications to proteomic and lipidomic analysis. For the case of off-line combination of FlFFF and MS, subcellular and extracellular species were separated by sizes first and then the collected organelle fractions of different sizes can be further investigated for the proteomic and lipidomic analysis using nanoflow LC-ESI-MS/MS. A miniaturiaed FlFFF can be utilized for the direct hyphenation to MS via electrospray ionization (ESI) or inductively couple plasma (ICP). The former enabled one to have top-down analysis of lipids from lipoproteins without extracting lipids and the latter led us to analyze metals from metalloproteins in blood plasmsa proteome. This presentation introduces recent works on the proteomic/lipidomic analysis of urinary exosomes from prostate cancer patients and on the direct metal analysis of metalloproteins from plasmsa samples with lung cancer.
