If you’ve ever been looking for just the right CRISPR vectors on Addgene and found instead ones that were… pretty close, or at least close enough, you’ve found yourself with a common dilemma. Request the vectors you can find and use them as-is, saving time and effort but risking ...
All plasmids rely on their host cell's replication machinery in order to replicate—but not always to the same extent. As described in our previous Origin of Replication post, DNA replication is initiated at the ori and may or may not be synchronized with the replication of the ...
If you’re depositing a pooled library with Addgene, you may be surprised to learn that we ask for an amplification protocol with your deposit. This is because repeated amplifications of pooled libraries can lead to issues such as recombination and loss of plasmid diversity, so ...
Modular cloning is a popular DNA assembly tool used to build single- and multi-gene constructs for a variety of applications. MoClo tools can be used in bacterial and cell-free expression systems, mammalian cells, yeast, flies, and even plants! In this blog we will review common ...
FITS In vitro CRISPR screens in immune cells have identified many putative regulators of immunity. However, in vitro screens cannot faithfully model the complex spatial, cellular, metabolic, and cytokine microenvironment that exists in vivo. Over the past five years, in vivo ...
Understanding the characteristics of natural plasmids and how they function in nature can inform us on how to create better recombinant vectors. In this blog post, we’ll define plasmid host range, identify a few of the features that confer broad host range in plasmids in nature, ...
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 ...
Primer design. Plasmid mapping. DNA sequence analysis. We all have our favorite tools for tackling these particular tasks, but they tend to be scattered about the internet. To help you keep your virtual molecular biology toolbox organized, today’s post features a list of free ...
