This video describes the microfluidic capillary electrophoresis technique to separate PCR amplicons based on their size. This technique helps in fragment sizing using fluorescent dyes and standard molecular size markers.
Protocol
1. Fragment Sizing of PCR Products Prior to starting, allow DNA dye concentrate, DNA gel matrix, DNA marker, DNA ladder and purified DNA samples to equilibrate to room temperature for 30 min. Set up the priming station Replace the syringe (see Table of Materials) when using a new batch of reagents. Adjust the base plate, and release the lever of the syringe clip and slide it up to the top position. Star…
