Over 75,000 pathogenic genetic variants have been identified in humans and cataloged in the ClinVar database. Previously developed genome editing methods using nucleases and base editors have the potential to correct only a minority of those variants in most cell types. But ...
ByBalázs Csoma, Hungarian Research Network CRISPR nucleases are remarkably precise molecular tools for cutting DNA. But “remarkably precise” does not mean “perfectly specific.” In reality, CRISPR nucleases occasionally make mistakes and cleave DNA sequences that only resemble ...
The genome-editing tool CRISPR is famously RNA-guided... except when it’s not. Turns out, carefully designed RNA-DNA hybrid strands work just as well—or maybe even better—at guiding Cas nucleases to specific genomic targets.
We recently updated our blog post on Prime Editing, and that meant rereading many of the original papers reporting various prime editing tools. These papers are chock full of great tips to guide your experimental design, especially the design of the RNA sequences you’ll use in ...
Prime editing is a versatile genome editing technology that allows precise modifications of DNA (replacements, small insertions, and deletions) without introducing DNA double-strand breaks (Anzalone et al., 2019; Chen & Liu, 2023). This method uses a prime editor (typically ...
We’ve all heard “Get that tube on ice!!” and “I hope it isn’t degraded” when scientists talk about their precious RNA samples. RNA is inherently less stable than most macromolecules used in scientific research such as DNA or protein. It comes as no surprise then that stability ...
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 ...
