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. WebDec 10, 2024 · Such products are short, usually 20 to 50 bp and appear at the bottom of the gel, far away from the DNA. If you see any faded band there, make sure you have primer dimers in the reaction. A thick band of genomic DNA, a linear and sharp band of PCR and a very sharp band of restriction digestion will appear in the gel.
