Branched polymer lables as drag-tags in free solution electrophoresis

摘要

End Labelled Free Solution Electrophoresis (ELFSE) provides a means of separating polymer molecules such as ssDNA according to their size, via free solution electrophoresis, thus eliminating the need for polymer separation via gels or polymer matrices. Here, end labels are provided that optimize branching architecture to increase hydrodynamic drag of the end label, and improve separation of polymer molecules by ELFSE.
