Originally published May 23, 2017 and last updated Jul 23, 2020 by Jennifer Tsang. CRISPR-Cas technology is constantly evolving. Variants of Cas proteins can be used for genome editing, activating gene expression, repressing gene expression, and much more. But there’s one thing ...
Originally published Feb 14, 2017 and updated Jun 24, 2020. Epigenetic modifications are an additional layer of control over gene expression that go beyond genomic sequence. Dysregulation of the epigenome (the sum of epigenetic modifications across the genome) has been ...
CRISPR has greatly enhanced the ability of scientists to make genomic alterations, bringing about a revolution in genome engineering, with new techniques rapidly being developed. Performing a CRISPR experiment requires delivery of, at minimum, two components: the Cas9 protein ...
By mutating one of two Cas9 nuclease domains, researchers created the CRISPR nickase. Nickases create a single-strand rather than a double-strand break, and when used with two adjacent gRNAs, can lower the probability of off-target editing. In this post, we’ll summarize how IDT ...
This post was updated on Jul 27, 2020. CRISPR, and specifically Cas9 from S. pyogenes (SpCas9), is truly an exceptional genome engineering tool. It is easy to use, functional in most species, and has many applications. That said, SpCas9 is not the only game in town, and other ...
Originally published Oct 11, 2016 and last updated Dec 22, 2020 by Benoit Giquel. CRISPR has taken the genome engineering world by storm owing to its ease of use and utility in a wide variety of organisms. While much of current CRISPR research focuses on its potential ...
Updated Mar 26, 2020. At their most basic level, CRISPR/Cas9 genome editing systems use a non-specific endonuclease (Cas9 or closely related Cpf1) to cut the genome and a small RNA (gRNA) to guide this nuclease to a user-defined cut site. After reading this post, we hope you ...
