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 ...
Bioblasts? Plasmagenes? In the 1940s and 50s, scientists were working to understand genetic cytoplasmic factors that could be transferred between cells. At the time, these extranuclear agents of heredity were thought of as everything from parasites, to symbionts, to genes and ...
Addgene’s plasmids are used with a wide variety of restriction enzyme-based cloning methods. Each method has its own pluses and minuses, but Golden Gate cloning has been especially useful within both the synthetic biology and genome engineering fields. We’ll walk you through how ...
This post is part of our ongoing Plasmids 101 series. Plasmids 101 will provide you with an overview of general molecular biology knowledge and techniques. If you are interested in reading more, you can find the rest of the Plasmids 101 posts here. Now that we have covered ...
There are many, many different types of experiments carried out by scientists every day. Although the designs and outcomes may vary, one thing should be present in every experiment-based investigation of a hypothesis: proper controls! For every experiment, an investigator needs ...
In a previous Plasmids 101 blog, we reviewed the salient features of several popular strains of E. coli for DNA propagation. While great for cloning purposes, these E. coli strains are not usually well suited for recombinant protein expression. Many challenges can arise when ...
In previous posts for our Plasmids 101 series, we examined a number of important plasmid elements – promoters, origins of replication, protein tags, and antibiotic resistance markers (just to name a few). In this edition, we’re going to take a look at a very interesting tool ...
