Cas9 is the genome editing tool of choice for a number of model organisms: mammalian cells, yeast, drosophila, plants, worms, zebrafish, frogs, some bacteria; but not thermophilic (high heat loving) bacteria. Until recently the only available Cas9 proteins were isolated from ...
Note: Cpf1 is also called Cas12a. There’s a new development for CRISPR-Cpf1 genome editing! A recent paper from Feng Zhang's lab describes how to use Cpf1 for multiplex genome editing. For a few reasons, Cpf1 is a simplified system for editing multiple targets compared to Cas9. ...
Last updated Oct 7, 2020 by Gabrielle Clouse. This post was contributed by guest bloggers Marcelle Tuttle and Alex Chavez, researchers at the Wyss Institute for Biologically Inspired Engineering. CRISPR/Cas9 is an enormously plastic tool and has taken the scientific world by ...
Update (November 18, 2016): Researchers from a variety of institutions recently reported their inability to recapitulate the results of Gao et al 2016 in a letter to Protein & Cell. Update (August 3rd, 2017) THE ORIGINAL NgAgo ARTICLE DISCUSSED IN THIS POST HAS BEEN ...
Note: Cpf1 is also called Cas12a. In 2015, Feng Zhang’s lab characterized two Cpf1 nucleases, distant cousins of well-known Cas9. Cpf1 cleaves DNA in a staggered pattern and requires only one RNA rather than the two (tracrRNA and crRNA) needed by Cas9 for cleavage. Now, two new ...
THE ORIGINAL NgAgo ARTICLE DISCUSSED IN THIS POST HAS BEEN RETRACTED AND FOLLOW UP STUDIES HAVE FAILED TO REPEAT THE RESULTS DISCUSSED BELOW Biologists are going gaga over the newest gene-editing protein - a DNA-cleaving Argonaute from Natronobacterium gregoryi, or NgAgo for ...
As evidenced by all the CRISPR publications, press, and plasmids out there, it’s obvious that CRISPR is a ground-breaking technology that’s already had a huge impact on research and will be affecting our everyday lives very soon. Not only is CRISPR having effects on various ...
