CRISPR construct design is a key step in the practice of genome editing, which includes identification of appropriate Cas proteins, design and selection of guide RNAs (gRNAs), and selection of regulatory elements to express gRNAs and Cas proteins. Here, we review the choices of CRISPR-based ...
The spacer sequence is located on the 5-prime end with respect to the PAM sequence, and the default spacer sequence length is 20 nucleotides. If necessary, we can change the spacer length using the functioncrisprBase::spacerLength. Let’s see what the protospacer construct looks like by using...
CRISPR genome editing technology is one of the fastest evolving fields in biology today. GENEWIZ’s years of experience and expertise in gene synthesis can provide you with cost-effective and time-sensitive CRISPR/Cas9 construct generation.
We can construct an RNA-targeting nuclease in way similar to a DNA-targeting nuclease by specifyingtarget="RNA". As an example, we construct below a CrisprNuclease object for the CasRx nuclease (Cas13d from Ruminococcus flavefaciens strain XPD3002): ...
Firstly, ssc-plasmid was used as the extension template for DNA polymerization-ligation to construct the mutation-containing ds-circular plasmid. The sequences of single- and multi-site mutagenic primers are listed in Table S1. To phosphorylate mutagenic primer, 5 µM DNA substrate was incubated...
For strand-specific RNA-Seq library construction, total RNA was first extracted from GM12878 cells using Trizol (Thermo Fisher Scientific), and 1 μg of RNA was used to construct the sequencing library with the NEBNext Ultra Directional RNA Library Prep Kit (NEB). The constructed libraries ...
Elimination of HIV DNA from infected individuals remains a challenge in medicine. Here, we demonstrate that intravenous inoculation of SIV-infected macaques, a well-accepted non-human primate model of HIV infection, with adeno-associated virus 9 (AAV9)-CRISPR/Cas9 gene editing construct designed for...
These processes draw attention to various features of internal validity, construct validi-ty, and external validity. As well, the credibility of supporting evidence is to be critically assessed with particular attention to optimism bias, financial conflicts of interest and publication bias. We ...

A detailed protocol to construct the multiplex guide RNA is presented in Supplementary Methods. The CRISPY-web service96 was employed to design the 20-nt-spacer sequence for each target gene. The GenBank sequences of P. aeruginosa PA14 (NC_008463.1), P. putida KT2440 (NC_008463.1), and ...
