WebThe method works by fixing the proteins in the gel and then oxidizing the sugar residues with sodium meta-periodate. The resulting aldehyde groups can then be reacted with an amine-containing dye. In older literature, this method is known as the periodate acid–Schiff (PAS) technique. A subsequent reduction step stabilizes the dye–protein bond.

An electric current is applied across the gel so that one end of the gel has a positive charge and the other end has a negative charge. Molecules migrate towards the opposite charge. A molecule with a negative charge will therefore be pulled towards the positive end. WebThe gel shift assay consists of three key steps: (1) binding reactions, (2) electrophoresis, (3) probe detection. The order of component addition for the binding reaction is often critical. Completed binding reactions are best electrophoresed immediately to preserve potentially labile complexes for detection. grantland rice 4 horsemen

WebAgarose gel electrophoresis is widely used to separate DNA (or RNA) of varying sizes that may be generated by restriction enzyme digestion (such as DNA fingerprinting / RFLP analysis) or by other means, such as the PCR. Important DNA molecules have an overall negative charge. WebAgarose gel electrophoresis is an easy and efficient method to separate, identify, and purify the DNA molecules. The location of DNA can also be determined with this method by staining with fluorescent dyes, which can detect up to 20 pg of double-stranded DNA by examination of the gel under UV.
