Even more elegant: Single injection CRISPR/Cas9 in C. elegans

Posted by Mary Gearing on Jul 7, 2015 11:36:00 AM

In the summer of 2013, a remarkable nine papers describing CRISPR/Cas9 genome engineering methods for C. elegans were released, signaling a new era in C. elegans research. Homology directed repair (HDR), which enables insertion of custom genomic modifications, is very robust in C. elegans, and the methods for HDR-mediated modification continue to be improved. New work from Bob Goldstein’s lab at the University of North Carolina has made CRISPR in C. elegans even easier - now, one can generate a fluorescent protein fusion, transcriptional reporter, and loss-of-function allele in just one injection step! The entire protocol takes about 2-3 weeks but requires less than eight hours worth of hands-on time.

An “elegans” Approach to Better CRISPR/Cas9 Editing Efficiency

Posted by Guest Blogger on Jan 27, 2015 10:13:47 AM

This post was contributed by Jordan Ward who is a postdoctoral fellow at UCSF.

Emerging CRISPR/Cas9 editing technologies have transformed the palette of experiments possible in a wide range of organisms and cell lines. In C. elegans, one of the model organisms which I use to study gene regulation during developmental processes, CRISPR/Cas9 allows us to knock out sequences and introduce mutations and epitopes with unprecedented ease. In the last year, several advances in C. elegans genome editing using CRISPR/Cas9 have emerged, which I will describe below. These new C. elegans approaches rapidly enrich for editing events without the need for any selective marker to remain in the edited animal. To my knowledge these approaches have not yet been extended to other organisms/cell lines, though it is likely that many aspects will broadly improve editing efficiency.
