Originally published Jan. 14, 2014 and updated Apr. 14, 2020. Any newcomer who joins a molecular biology lab will undoubtedly be asked to design, modify, or construct a plasmid. A plasmid is a small circular piece of DNA found in bacterial cells, and someone new to plasmids may ...
Plasmid incompatibility is defined as the inability of different plasmids to be maintained in one bacterial cell. In this Plasmids 101 post, we’ll cover why this happens, how it might affect your work, and how understanding it can be used for good. First, why are plasmids ...
As with DNA isolation, scientists commonly rely on RNA isolation kits to make their life easier. Recently, we published a blog on DNA purification without a kit that outlined several reasons why doing something without a kit has advantages: less plastic waste, less expense, and ...
Are you a grad student, postdoc, or bench scientist who began working remotely recently? Most of us at Addgene began working from home last week to flatten the curve, but working remotely can be more difficult if your work is based in the lab. If you’re unsure what to do during ...
David Liu’s lab created the first base editor in 2016 (Komor et al., 2016) and since then has been trying to expand their precision editing capabilities. Base editors make specific DNA base changes and consist of a catalytically impaired Cas protein (dCas or Cas nickase) fused ...
Adeno-associated virus (AAV) is a popular tool for gene delivery, but it has a drawback: how do you ensure your gene goes where you want it to? Knowing that a gene is expressed in a particular cell type is important not only for translational research, such as gene therapy, but ...
In this quarterly blog series, we’ll highlight a few of the new CRISPR plasmids available at Addgene. We will still periodically focus on specific CRISPR plasmid tools more in-depth, but we hope that this blog series will help you find more new CRISPR tools for your research! ...
