Gel electrophoresis of PCR products is the standard method for analyzing reaction quality and yield. PCR is a relatively simple and inexpensive tool that you can use to focus in on a segment of DNA and copy it billions of times over. When the red and black leads are plugged into a power supply the DNA migrates through the gel toward the positive charge due to the net negative charge of the molecule. The rate of PCR fingerprinting interassay and intercenter reproducibility was low and was only increased when DNA samples were extracted at the same time and amplified with the same reaction mixtures. The results after the first gel electrophoresis indicated the presence of PCR product. Guidelines for the PCR Amplification & Gel Electrophoresis Lab Report.
