Electrophoretic mobility gel shift
WebOct 15, 2016 · Interactions between proteins and nucleic acids are frequently analyzed using electrophoretic mobility shift assays (EMSAs). This technique separates bound protein:nucleic acid complexes from free nucleic acids by electrophoresis, most commonly using polyacrylamide gels. The current study utilizes r … WebThe electrophoretic mobility of the resulting tailed duplex on a nondenaturing gel reflects the length of both the RNA–RNA duplex and the attached poly(A) tail. The contribution of the poly(A) to mobility can be determined by comparison with an RNA sample deadenylated …

WebJan 8, 2009 · Introduction. The electrophoretic mobility shift assay (EMSA), also known as “gel shift assay”, is used to examine the binding parameters and relative affinities of protein and DNA interactions. We produced recombinant CCA1 protein and tested its binding affinity for the promoter fragments that contain CBS (AAAAATCT) or evening … 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 based on nondenaturing polyacrylamide gel electrophoresis is a simple, rapid, and sensitive method for the study of the interaction of transcription factors with DNA in vitro. It relies on a change in the electrophoretic mobility of a DNA fragment when bound to an interacting protein. WebJul 26, 2007 · The electrophoresis mobility shift assay (EMSA) is a rapid and sensitive method to detect protein–nucleic acid interactions1–6.Itis based on the observation that the electrophoretic mobility of a protein–nucleic acid complex is typically less than that of the free nucleic acid (Fig. 1). The current, widely-used assay differs little
