WebJul 1, 2013 · In an electrophoretic mobility-shift assay (EMSA, or simply "gel shift"), a (32)P-labeled DNA fragment containing a specific DNA site is incubated with a cognate DNA-binding protein. The protein-DNA complexes are separated from free (unbound) DNA by electrophoresis through a nondenaturing polyacrylamide gel. WebJun 10, 2015 · This amphiphilic DNA, which we term lipid-DNA, is synthesized in advance and is blended into a block copolymer gel to induce sequence-dependent DNA retention during electrophoresis. Furthermore, we demonstrate and characterize the programmable mobility shift of matching DNA in such reversible gels both in thin films and …
