The CRISPR-Cas9 system has revolutionized the field of genome engineering with limitless applications in disease therapeutics, drug discovery, agriculture, biofuels, and much more. This comprehensive guide addresses all the main steps in the CRISPR workf
expression, and targeted interference (Jinek et al.2012). In the acquisition stage, upon recognizing an exogenous DNA sequence, the system integrates this sequence into the host genome between the repeat sequences at the 5' end of the CRISPR locus. During expression, the CRISPR locus ...
How does our gRNA design tool work? The IDT Custom Alt-R™ CRISPR-Cas9 guide RNA design tool can be used to help you design gRNA sequences for use with Cas9 with high on-target and low off-target activity in human, mouse, rat, zebrafish, and C. elegans for your specific research ...
Although Cas9 is the most widely CRISPR variant used in genome engineering experiments, it does have certain limitations. First, its complementarity specifications are not very stringent - it can recognize other PAM sequences, like 5’-NAG-3’and 5’-NGA-3’, which results in off-target editin...
Deubiquitination is suggested to be necessary for full NLRP3 activation. This modification may be involved in the rapid activation of NLRP3, which can be triggered after a short priming time (30 min or less) [98]. After LPS or Pam3CSK4 exposure, Abraxas brother protein 1 binds NLRP3 ph...
A guide specific to U8-3, the design of which was facilitated by the absence of a relevant protospacer adjacent motif (PAM) sequence in the other zebrafish U8 gene copies, was used to delete 54bp from the U8-3 gene locus, herein referred to as Δ54U8-3 (see Figure S6A and S6B). ...
; (B) The main reason why we would like to control living systems is to control how one cell behaves and in this way, determine what it does e.g. differentiation. The tools to achieve such fates are only beginning to come of age. In this review, some of the most innovati...

Phages could also avoid CRISPR–Cas systems by producing mutations at PAM sites [93]. Furthermore, phages have anti-abortive infection machinery, such as mutations in the nucleotide metabolism genes of Lactococcus spp. phages that allow them to escape from AbiQ mechanism [94] and phage TE ...
