Protocol exploits differences in electrophoretic mobility through a nondenaturing polyacrylamide gel between a rapidly migrating target DNA and a more slowly migrating DNA-protein complex. - [Read Gel Retardation Assays for DNA-binding Proteins Protocol]
A non-radioactive electrophoretic mobility which works quite well using biotin and streptavidin detection. Non-specific and specific competititor, oligo labeling, Binding Reaction. Pierce - [Read Introduction to the EMSA (Gel Shift) Technique]
Dnase I is used to fragment a radiolabeled target DNA in the presence and absence of a nuclear extract. A "footprint" is generated when a protein binds to the target and protects a specific segment of DNA from the nucleolytic activity of Dnase I. By comparing the electrophoretic mobility of the Dnase I cleavage products to those of a sequence ladder derived from the same DNA fragment, the position(s) of the DNA sequences recognized by DNA-binding proteins can be determined. - [Read Mapping Protein-binding Sites on DNA by Dnase I Footprinting Protocol]
Single-strand confirmation polymorphism analysis (SSCP) is a powerful and robust method for the detection of DNA sequence changes (single-base substitutions) based on shifts in electrophoretic mobility. In this protocol, the target sequence is simultaneously labeled and amplified, then heat-denatured and resolved by non-denaturing polyacrylamide gel electrophoresis. - [Read Single-Strand Conformation Polymorphism Analysis Protocol]
The target sequence is simultaneously labeled and amplified, then heat-denatured and resolved by non-denaturing polyacrylamide gel electrophoresis. Differences in sequence alter the conformation of the DNA and hence its electrophoretic mobility and, because of the high resolution of polyacrylamide gels, most conformational changes caused by subtle changes in sequence can be detected. - [Read Single-Strand Conformation Polymorphism Analysis Protocol]
