Witryna10 gru 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. WitrynaGel electrophoresis is the most common method used to detect products from PCR. Each gel electrophoresis should contain a positive control and a negative control. The positive control should consist of a segment of DNA of known size (preferably of the same size as the target amplicon). The negative control is only buffers and reagent …
