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. WebElectrophoresis gels are formulated in buffers that enable electrical current to flow through the matrix. The prepared solution is poured into the thin space between two glass or plastic plates that form a cassette. This …

WebCharged molecules move through a gel when an electric current is passed across it. 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. WebOct 4, 2024 · It’s called “electrophoresis” because, to make the molecules move through the gel, an electrical current is applied. Because the sugar-phosphate backbone of the DNA has a negative electrical charge, the electrical current tugs the DNA along with it through the gel.
