	*If you are interested in cutting near the ends of the linear DNA fragment, note that some enzymes do not cut efficiently at the ends of linear DNA. So include extra bases to increase the efficiency of cutting. Many enzymes work with 4 bases supposedly but XhoI was found to require more than 4 bases (8 bases was used successfully). Thus, to be on the safe side, use 8 bases whenever possible. [http://www.neb.com/ NEB] has more information [http://www.neb.com/nebecomm/tech_reference/restriction_enzymes/cleavage_linearized_vector.asp here]. Read the information at NEB carefully ... they recommend adding 4 bases to the numbers listed in their table.		*If you are interested in cutting near the ends of the linear DNA fragment, note that some enzymes do not cut efficiently at the ends of linear DNA.

	*Tom was once having some trouble with failed restriction digests. He called NEB and they recommended doing the digest in a larger volume. Therefore, the Knight lab typically does digests in either 50 μL or 100 μL volumes rather than the 20 μL volume that the Endy lab uses. If the sample needs to be concentrated, some method of [[Purification of DNA \| DNA purification]] is used.		*Tom was once having some trouble with failed restriction digests.
