Electrophoresis Mobility Shift Assay
[Abstract]  Protein (transcription factors and/or transcription cofactors)-binding to DNA is a critical event in regulation of transcription. Electrophoresis Mobility Shift Assay (EMSA), also known as gel shift assay, is a useful tool to detect protein- or protein complex-DNA/RNA interaction and to evaluate DNA binding specificity of transcription factors in vitro. Here we describe a simple method for EMSA with fluorescent dye-bound oligo DNA probes and recombinant protein expressed in bacterial ...

EMSA Analysis of DNA Binding By Rgg Proteins
[Abstract]  In bacteria, interaction of various proteins with DNA is essential for the regulation of specific target gene expression. Electrophoretic mobility shift assay (EMSA) is an in vitro approach allowing for the visualization of these protein-DNA interactions. Rgg proteins comprise a family of transcriptional regulators widespread among the Firmicutes. Some of these proteins function independently to regulate target gene expression, while others have now been demonstrated to function as ...

A General EMSA (Gel-shift) Protocol
[Abstract]  An electrophoretic mobility shift assay (EMSA), also referred to as mobility shift electrophoresis, a gel shift assay, gel mobility shift assay, band shift assay, or gel retardation assay, is a common technique used to study protein-DNA or protein-RNA interactions. The control lane (the DNA/RNA probe without protein present) will contain a single band corresponding to the unbound DNA or RNA fragment. If the protein is capable of binding to the fragment, the lane with protein present will ...
