Scientists use deep mutational scanning to simultaneously test how multiple amino acid changes affect a protein of interest’s function. This technique relies on the generation of a plasmid library that expresses all desired variants of a protein. Applying a selective pressure ...
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 ...
One of the most powerful strategies to investigate a gene's function is to inactivate, or "knockout", the gene by replacing it or disrupting it with an piece of DNA designed in the lab. Specially constructed plasmids can be used to replace genes in yeast, mice, or Drosophila ...
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 ...
This post was contributed by guest blogger, Jessica Sacher, a microbiology PhD student at the University of Alberta studying with the Szymanski lab. Reasons to study how a phage recognizes its host Bacteriophages (viruses that prey on bacteria) may be the most numerous and most ...
