Web27 apr. 2024 · You can identify the linear DNA form on an agarose gel by comparing uncut plasmid DNA with a sample of the plasmid that has been linearized using a restriction enzyme. If you get linear DNA when you are hoping for supercoiled (e.g. after DNA plasmid preps), it is due to nuclease contamination or harsh treatment during purification. WebDepending on the DNA size and resolution of DNA fragments, one has to decide the gel run time. Step 7: Once the gel run is over, turn off the power supply and disconnect the …
