As a plasmid repository, we are no strangers to cloning. If you’re reading this, then chances are you have been in the cloning trenches yourself. Modular cloning, or MoClo, is a systematic cloning strategy designed by synthetic biologists to perform large scale, one-tube cloning ...
Plasmids need antibiotic resistance genes so that you can specifically isolate bacteria containing your constructs of interest. But does it matter which antibiotic resistance gene you select? In this blog, we’ll break down the mechanism of action of the most common antibiotic ...
We are excited to announce the fourth edition of our popular eBook, Plasmids 101, is now available!
If you’ve ever used Golden Gate Assembly for cloning, you might be familiar with the rules of thumb for designing your overhang sets. But are those rules the best way to design GGA overhang sets, particularly for high-complexity reactions?
Around 20% of human genes have no known function or a poorly defined function (Wood, et al). In the microbial world, approximately 50% of predicted genes have unidentified roles as well (Vanni, et al). Is it true that this many genes are truly dispensable or are the current ...
When performing restriction digests on plasmids at Addgene, we sometimes observe something odd in our uncut DNA control: a band or two appear on an agarose gel at notably higher molecular weights than expected, given the size of the plasmid. This is seen only in the uncut DNA; ...
Promoters control the binding of RNA polymerase and transcription factors. Since the promoter region drives transcription of a target gene, it therefore determines the timing of gene expression and largely defines the amount of recombinant protein that will be produced. Many ...
