WebOct 15, 2016 · In summary, we have developed an electrophoretic mobility shift assay method using an agarose gel and low-conductivity buffer system that requires only standard molecular biology reagents and equipment. The assay allows for rapid, quantitative analysis of protein/RNA interactions, requiring less than 90 min from gel pouring to data acquisition. WebJan 1, 2007 · The gel electrophoresis mobility shift assay (EMSA) is used to detect protein complexes with nucleic acids. It is the core technology underlying a wide range of qualitative and quantitative analyses for the characterization of interacting systems. In the classical assay, solutions of protein and nucleic acid are combined and the resulting ...
Electrophoretic Mobility Shift Assay for the Analysis of …
A mobility shift assay is electrophoretic separation of a protein–DNA or protein–RNA mixture on a polyacrylamide or agarose gel for a short period (about 1.5-2 hr for a 15- to 20-cm gel). The speed at which different molecules (and combinations thereof) move through the gel is determined by their size and charge, and to a lesser extent, their shape (see gel electrophoresis). The control lane (DNA probe without protein present) will contain a single band corresponding to the unbou… Webelectrophoresis [e-lek″tro-fo-re´sis] the movement of charged particles suspended in a liquid on various media (e.g., paper, gel, liquid) under the influence of an applied electric field. adj., adj electrophoret´ic.

WebThe electrophoretic mobility of an ion, μep (ion), can be related to the limiting ionic equivalent conductivity, λeq, by. [1] where F is the Faraday constant ( F =9.6487×10 4 A s mol −1 ); λeq (cm 2 mol −1 Ω −1) is related, by the Stokes law, to the charge of the … WebJul 3, 2024 · Using structure-based design and virtual screening of the NCI Diversity Compound Library, 12 shortlisted compounds were tested for their ability to interfere with the binding of Vezf1 to DNA using electrophoretic gel mobility shift assays. We identified one compound, T4, which has an IC50 of 20 μM. WebThe electrophoretic mobility shift assay (EMSA), also known as gel retardation or band shift assay, is a rapid and sensitive means for detecting sequencespecific DNA-binding proteins (1,2). This assay can be used to determine, in both a qualitative and quantitative manner, if a particular transcription factor is present within the nuclei of the ... great depression assignment
