Northwestern Team Develops System for Simplifying Sample Cleanup in Top-Down Proteomics
The lab of Northwestern University researcher Neil Kelleher has developed an on-line system for clean up of top-down proteomics samples following gel eluted liquid fraction entrapment electrophoresis (GELFrEE) fractionation. The system, detailed in a paper published this month in the Journal of Proteome Research, uses asymmetrical flow field-flow fractionation (AF4) to address what is a key challenge in top-down proteomic workflows, and could make top-down approaches more widely shareable as well as improve their applicability to clinical work, Philip Compton, director of instrumentation at NorthWestern's Proteomics Center of Excellence and an author on the paper, told GenomeWeb.
