While much of CRISPR research has focused on genome editing, numerous discoveries have been made using the Cas9 nuclease in the absence of genomic alterations. These studies utilize a catalytically inactive form of Cas9 known as dCas9 (Jinek et al., 2012). Like Cas9, dCas9 can ...
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 new CRISPR tools for your research! This ...
The catalytically dead Cas9 protein (dCas9) is well known for its ability to bind DNA targets without changing them. Thus, it has been widely adapted for a wide variety of applications: base editing, CRISPR activation and inhibition, among others. Over the past few years, dCas9 ...
The vast majority of bacteria are undomesticated which limits the tools scientists can use to study them. For example, gene knockdown with CRISPR interference (CRISPRi) has been limited to lab-adapted bacteria because it has been challenging to introduce CRISPRi machinery into ...

Mutagenesis is a tool that both evolution and molecular biologists use to tinker with DNA. Making changes to a DNA sequence can help scientists identify and/or facilitate the evolution of new phenotypes, and forward genetics harnesses this at a large scale by screening diverse ...
This post was contributed by Greg Dingle, a software engineer with the Chan Zuckerberg Initiative. We hereby announce the general availability of new a tool for CRISPR scientists––CrispyCrunch! CrispyCrunch is a web app that helps scientists design and analyze batches of CRISPR ...
This post was contributed by Kutubuddin Molla, a Fulbright Visiting Scholar at the Pennsylvania State University. Imagine you are dealing with a defective gene, Xm, the sequence of which is identical to the correct gene, Xw, except for a single base. If you heard about CRISPR, ...
