Originally published Mar 3, 2016 by Mary Gearing and last updated Apr 13, 2021 by Will Arnold. Although CRISPR systems were first discovered in bacteria, most CRISPR-based genome engineering has taken place in other organisms. In many bacteria, unlike other organisms, ...
Originally published May 3, 2017 and last updated Sep 24, 2020 This post was contributed by guest blogger, Addgene Advisory Board member, and Institute Scientist at the Broad Institute, John Doench. CRISPR technology has made it easier than ever both to engineer specific DNA ...
Originally published Jan 28, 2016 and last updated Sep 10, 2020 by Jennifer Tsang. CRISPR makes it easy to target multiple loci - a concept called multiplexing. Since CRISPR is such a robust system, editing or labeling efficiency doesn’t usually change when you add multiple ...
This blog post was originally written by Caroline LaManna, published Mar 8, 2016. The updated and expanded version by Nyla Naim was published Sept 3, 2020. Scientists around the world have been making major improvements to CRISPR technology since its initial applications for ...
Originally published Nov 12, 2015 and last updated Aug 20, 2020. Cas9 can be used to modify any desired genomic target provided that (1) the sequence is unique compared to the rest of the genome and (2) the sequence is located just upstream of a Protospacer Adjacent Motif (PAM ...
Originally published Nov 30, 2017 and updated Jul 31, 2020. Cas13 enzymes are quickly becoming major players in the CRISPR field. Just a year after Feng Zhang’s lab identified Cas13a (C2c2) (Abudayyeh et al., 2016) as a RNA-targeting CRISPR enzyme, they adapted Cas13b for ...
