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 ...
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 ...
Base editors create specific point mutations in the genome, but they’re inefficient compared to CRISPR/Cas9 edits that rely on double strand DNA breaks. Due to this inefficiency it is crucial for scientists to not only easily identify base editing events in real-time but also ...
Originally published Dec 7, 2017 and updated Jul 2, 2020. Promoters may be the star of gene regulation, but enhancers and chromatin looping play important supporting roles. Enhancers are cis regulatory DNA sequences that, when bound by transcription factors, can increase a ...
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 ...
If you’re using CRISPR to make a genome edit, how do you know if your CRISPR experiment was successful in your organism or cell type? You can use DNA sequencing or other molecular cloning techniques to determine CRISPR/sgRNA efficiency of an experiment and confirm the correct ...
Adenine base editors (ABE) mediate A•T-to-G•C base changes (Figure 1), but it can be challenging to make these base changes, especially in primary human cells. Now, scientists at Beam Therapeutics have found a way to improve editing in primary human cells (Gaudelli et al., ...
