Members of the bacterial world produce an assortment toxins to claim territory or kill competing microorganisms, but did you know bacteria also produce substances toxic to themselves? What are toxin-antitoxin systems? These toxic substances are part of toxin-antitoxin systems ...
This post was contributed by Laura Lee, a graduate student at Stanford University. Arabidopsis is a fantastic model organism for many reasons, not the least of which is ease of transformation. There are many motivations to generate transgenic Arabidopsis, from studying ...
This post was contributed by Jake Watson and Javier García-Nafría from the MRC Laboratory of Molecular Biology. Plasmid cloning is an essential part of any molecular biology project, yet very often, it is also a bottleneck in the experimental process. The majority of current ...
This post was contributed by guest bloggers Becky Kucera, M.Sc. and Eric Cantor, Ph.D. from New England Biolabs. Golden gate assembly limitations Embraced by the synthetic biology community, Golden Gate Assembly is commonly used to assemble 2–10 DNA fragments in a single ...
A similar genetic code is used by most organisms on Earth, but different organisms have different preferences for the codons they use to encode specific amino acids. This is possible because there are 4 bases (A, T, C, and G) and 3 positions in each codon. There are therefore 64 ...
Every few months we highlight a subset of the new plasmids in the repository through our hot plasmids articles. These articles provide brief summaries of recent plasmid deposits and we hope they'll make it easier for you to find and use the plasmids you need. If you'd ever like ...
Researchers express genes of interest from plasmids in order to study gene function or to engineer cells for specific purposes. Unfortunately, plasmid copy numbers vary within cell populations and over time resulting in variable gene expression that can impact observed ...
