Each target site is placed between 700 and 900 bp from each other, allowing for sufficient flexibility of the plasmid DNA relative to the known persistence length of DNA. 4. Add 1/10 volume of gel loading dye to each restriction digest, tap to mix and quick spin. . . Select restriction enzymes to digest your plasmid. . . Select restriction enzymes to digest your plasmid. CHE 341 Lab 8 Lesson Restriction Digest. 5. . . Martee Larson, Lauren Lindsey, Shannen Mahal, Nicholas Goeman. 5. Restriction Endonuclease Digestion of Plasmid DNA 1. Unless directed otherwise, keep all tubes on ice at all times. .
. The exact mobilities of the 3 forms will vary based on conditions, but closed circular DNA will usually migrate faster than the other two because of its. Several restriction enzymes (REs) will be used to digest the plasmid pCMV-GFP to build a restriction map of the plasmid.

Martee Larson, Lauren Lindsey, Shannen Mahal, Nicholas Goeman. The fragments produced have a known sequence that can be ligated to complementary sequences and be cloned by the cell’s molecular machinery. .
As always, goggles must also be worn.
Pure DNA is fairly stable, but restriction enzymes are highly labile and will degrade if left at room temperature. Reaction volumes should be 25-50 µl and the amount of enzyme added should not exceed 10% of the volume due to the glycerol content. . As always, goggles must also be worn.
