Choosing restriction sites
Set up restriction digestsfor your insert (or donor plasmid) and plasmid backbone. Because you lose some DNA during the gel purification step, it is important to digest plenty of starting material. We recommend 1.5-2μg of insert and 1μg of plasmid backbone. It is also critical that as much of the backbone plasmid … See more Now that you’ve cut your insert and vector, unfortunately you can’t just throw the digestion mixtures together. You need to isolate your insert and backbone from the enzymes used to digest them as well as any pieces cut out or … See more In the ligation step, you mix your purified, cut backbone and insert in a single tube allowing the compatible overhangs generated by restriction digestion to anneal to one … See more Once it looks like your ligation has worked, you will need to pick individual bacterial colonies and check them for successful ligation. Pick 3-10 … See more Transformyour ligation reaction into your bacterial strain of choice. Follow the manufacturer’s instructions for your competent cells. For most standard cloning, you can … See more WebA restriction enzyme is a DNA-cutting enzyme that recognizes specific sites in DNA. Many restriction enzymes make staggered cuts at or near their recognition sites, producing ends with a single-stranded overhang. If two …
Choosing restriction sites
Did you know?
WebThis step uses restriction enzymes and DNA ligase and is called a ligation. After a ligation, the next step is to transfer the DNA into bacteria in a process called transformation. Then, we can use antibiotic selection and DNA analysis methods to identify bacteria that contain the plasmid we’re looking for. WebBy choosing restriction sites with compatible ends that destroy the recognition site when ligated to one another, parts can be combined together and the original flanking sites re-used for the next round of …
