Plasmids 101: Restriction Cloning. By Tyler Ford. Tyler Ford February 18, 2016. When cloning by restriction digest and ligation, you use restriction enzymes to cut open a plasmid (backbone) and insert a linear fragment of DNA (insert) that has been cut by compatible restriction enzymes. An enzyme, DNA ligase, then covalently binds the plasmid. 3 µL 10x BSA (if recommended) x µL dH 2 O (to bring total volume to 30µL) *Pro-Tip* The amount of restriction enzyme you use for a given digestion will depend on the amount of DNA you want to cut. By definition: one unit of enzyme will cut 1 µg of DNA in a 50 µL reaction in 1 hour Restriction enzymes are naturally occurring bacterial endonucleases that recognize a large range of DNA sequences. Given the variety of these enzymes and the unique sites they recognize, restriction digests have become the most widely used method scientists employ to selectively move a specific piece of DNA from one plasmid to another , including double digestion buffers DoubleDigest conveniently calculates the best enzymatic reaction buffer, enzyme concentrations, incubation conditions, and any additives needed in your double digest reaction.
