This post was contributed by guest blogger Lydia Morrison from New England Biolabs. What is DNA assembly? In the context of cloning, DNA assembly refers to a method of physically joining multiple fragments of DNA to create a synthetically designed DNA sequence. There are ...
When facing a cloning project, scientists are no longer limited to traditional restriction enzyme cloning. Instead, you can choose a molecular cloning technique that will work well with a given set of resources, time, and experimental needs. Since its invention in the late ...
Restriction enzyme cloning is the workhorse of molecular cloning; however, one of its biggest limitations is that sequence modifications can only be made at restriction enzyme cut sites. The lambda red system is an alternative method that can be used for cloning or genome ...
If you’re into cloning, you’re probably aware that there are several methodologies currently available for approaching it. These include the traditional restriction enzyme/ligase-mediated method, the more recently developed Gibson Assembly Cloning and Gateway® cloning ...
This post was contributed by guest blogger Meghan Monroy, a graduate student in Protein Science at the University of Connecticut. Molecular cloning is the isolation, insertion and amplification of a recombinant DNA without sequence alteration. Molecular cloning techniques are ...
Topoisomerase based cloning (TOPO cloning) is a DNA cloning method that does not use restriction enzymes or ligase, and requires no post-PCR procedures. Sounds easy right? The technique relies on the basic ability of complementary basepairs adenine (A) and thymine (T) to ...
Have you ever tried digesting with XbaI or ClaI restriction enzymes and gotten unusual or unexpected results? Or considered why DpnI will degrade your template DNA from a PCR reaction but not the newly synthesized product from a site-directed mutagenesis experiment? The answer ...
In its simplest form, PCR based cloning is about making a copy of a piece of DNA and at the same time adding restriction sites to the ends of that piece of DNA so that it can be easily cloned into a plasmid of interest. You can use similar processes to add overhangs to your ...
