FLOWABLE NETWORKS AS EQUILIBRIUM DNA-SEQUENCING MEDIA IN CAPILLARY COLUMNS

We describe a novel class of materials that self-assemble into equilib rium network structures with a well-defined pore size that permit elec trophoretic DNA sequencing, in capillary columns, with excellent repro ducibility. These polymers, poly(ethylene glycols) end-capped with mic elle-forming fluorocarbon tails, form flowable aqueous networks that h ave unusual rheological properties.
