Abstract

A multiplexed hollow fiber flow field-flow fractionation (MxHF5) is introduced to increase throughput of an HF5 channel system for semi-preparative purposes. HF5, a cylindrical version of the flow field-flow fractionation (FlFFF) operated with a porous, hollow fiber membrane by controlling the ratio of radial and axial flow rates, is capable of fractionating proteins, cells, and macromolecules by size. An advantage of HF5 is its inexpensive channel construction, allowing for disposability that can reduce run-to-run carryover problems. MxHF5 constructed in this study was made with six parallel HF5 modules connected to seven-port manifolds for the semi-preparative scale separation of proteins or biological particles. For the evaluation of MxHF5 separation efficiency, protein standards were utilized to test peak recoveries, band broadening, and throughput. The assembly showed the possibility of handling up to 50 μg of proteins without incurring overloading. The developed channel was applied to demonstrate size sorting of lipoproteins for the future study of size dependent lipidomic and proteomic analysis. The current trial offers a unique advantage of scaling up HF5 separation without using wide-bore, hollow fibers which sacrifice separation speed.
