This post was contributed by guest blogger Tessa Cressey. The highly pathogenic Ebola virus belongs to the group of nonsegmented negative sense RNA viruses, along with other viruses that cause disease in humans such as measles, mumps, and rabies. Research on Ebola virus has been ...
Over the past decade, scientists have developed and fine tuned many different ways to clone DNA fragments which have provided appealing alternatives to restriction enzyme cloning. These newer technologies have become more and more common, and for good reason. They offer many ...
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 to the new ...
Site-directed mutagenesis (SDM) is one of the key tools researchers use to prove causation in molecular biology and genetics. It can be used to characterize the function of certain regions in a promoter or gene, as well as to study the effects of inactivating/activating ...
One of the best things about sharing plasmids through Addgene is that we provide an added level of confidence in the plasmids we distribute through our quality control processes. Every plasmid we receive is rigorously verified before becoming available to the community. This is ...
At Addgene we're continually impressed with the amazing plasmid technologies developed by our community of depositors. With over 40,000 plasmids avaliable in the repository, we can't give all of them attention they righlty deserve, but, in this post, we'll provide a small ...
First described in the 1980s, protein tags are now one of the most useful items in a scientist’s toolbox. As we’ve covered in Plasmids 101, tags can help you determine localization of a protein of interest, purify it, or determine its expression level without the need for a ...
