miniPCR bio TM Chopped! Using CRISPR/Cas9 to cut DNA - Student's Guide Version: 1.0 - Release: May 2022 - © 2022 by miniPCR bio™ Student's Guide P./26 5. Press the "Run" button • Check that the green light beside the power button remains illuminated. 6. Conduct electrophoresis for 20-30 minutes • The colored dye should progress to about half the length of the gel. • Longer electrophoresis times will result in better size resolution. 4. Place the orange cover on the blueGel™ electrophoresis system • To prevent fogging, make sure that ClearView™ spray has been evenly applied to the inside of the orange cover. • Match the positive and negative electrode signs on the orange lid with the corresponding positive and negative signs on the blue base. • The electrodes of the lid should be aligned with the metal leads on the base. • The orange lid should sit flush with the blue base using little force. Gel electrophoresis – Visualizing results 1. Press the "light bulb" button to turn on the blueGel™ transilluminator • For best viewing, dim lights or use Fold-a-View™ photo documentation hood with a smartphone camera. • Gels may be viewed at the end of the run or periodically throughout the run. • If the image appears hazy, wipe off the inside of the orange cover and reapply ClearView™ spray. 2. Ensure that there is sufficient DNA band resolution • Run the gel longer if needed to increase resolution. 3. Document your results • Place Fold-a-View™ photo documentation hood on the blueGel™ electrophoresis system to take a picture with a smartphone or other digital camera. • Compare the bands from the DNA samples to the ladder to obtain size estimates. Fast DNA Ladder 3.
