We describe five distinct zebrafish U6 promoters for sgRNA expression and demonstrate efficient multiplex biallelic inactivation of tyrosinase and insulin receptor a and b, resulting in defects in pigmentation and glucose homeostasis.
The U6-sgRNA-EFS-GFP vector was derived from the lentiCRISPR-Cas9 plasmid (Addgene: # 49535) by removing the hCas9 cDNA and replacing the Puro cassette with GFP reporter. pi : 2374
Examples of promoters used to construct RGE vector: Pol II promoter: CaMV 35S promoter, maize UBIQUITIN promoter, rice ACTIN promoter, etc. Pol III promoter: snoRNA U3 promoter, snoRNA U6 promoter, etc.
The RNA-guided Cas9 nuclease, from the type II prokaryotic Clustered Regularly Interspersed Short Palindromic Repeats (CRISPR) adaptive immune system, has been adapted and utilized by scientists to edit the genomes of eukaryotic cells. Here, we report the development of a viral mediated CRISPR/Cas9 system that can be rendered inducible utilizing doxycycline (Dox) and can be delivered to cells ...
The sgRNA targets <i>ADH1</i>. CRISPR activity measured in % of homozygous or biallelic stable mutants in the second generation after transformation (T2). Each dot represents an independent T2 family. Bold and underlined: Most active construct(s) for each panel.</p
The CRISPR/Cas9 system requires both the Cas9 nuclease and a single guide RNA (sgRNA). The sgRNA must contain a ~20-base sequence (crRNA) specific to the target DNA and an invariant Cas9 nuclease-recruiting sequence (Figure 1). Expression of sgRNA is driven by a human U6 promoter (Figure 1). A downstream mCherry reporter on the same lentiviral ...
Feb 08, 2018 · U6 promoters have been used for single guide RNA (sgRNA) transcription in the clustered regularly interspaced short palindromic repeats/CRISPR-associated protein (CRISPR/Cas9) genome editing system.

Because it needs U6 promoter to have a ‘G’ base at the transcription start site. Hence, we recommend finding a 20bp genome target starting with the base ‘G’. If you have to use other bases at the starting position of your genome target, you could add an additional ‘G’ to the front of your target.
Features of all vectors used for in vivo sgRNA expression in TRIP-CRISPR stocks: vermilion as a selectable marker attB sequence to allow for phiC31 targeted integration at genomic attP landing sites ubiquitous sgRNA expression driven by one or more RNA polymerase III-dependent promoters from U6 snRNA genes flySAM2.0 (Jia et al., 2018) ubiquitously expresses one sgRNA containing MS2 loops from ... This comprises a lentiviral vector containing the mouse U6 promoter driving sgRNA expression (Addgene 51024). It also contains an expression cassette consisting of a cytomegalovirus (CMV) promoter, a puromycin- resistance gene cassette, and an mCherry gene for selection purposes. Trypsin-EDTA (0.05%) (e.g., Life Technologies 25300-054)
SaCas9-sgRNA. Supplementary Methods. Plasmid design . The pX458 vector was a gift from Feng Zhang (Addgene plasmid # 48138), and an AAV vector containing inverted terminal repeats (ITRs), the liver-specific-1 (LP1) promotor, SaCas9 and the U6 promotor was constructed and used for AAV packaging.

Results Cloning of CRISPR-Bac We modeled CRISPR-Bac (Figure 1) after the pX330 plasmid system in which a humanized version of the Cas9 enzyme from Streoptococcus pyogenesis co-expressed with a chimeric sgRNA driven by a U6 promoter (Cong et al., 2013). The pRSGEP-U6-sg-EF1-Puro sgRNA Cloning and Expression Vector is a human immunodeficiency virus (HIV) lentiviral vector with a constitutive U6 promoter to express sgRNA constructs and human UbiC promoter to express a puromycin-resistance gene.

plasmid contains the U6 promoter, which drives RNA expression in mammalian cells and the scaffold for the sgRNA with a convenient cloning locus that is flanked by BsmBI restriction sites for facile cloning of the target sequence. The plasmid also contains the EF1alpha promoter,
U6promoter-sgRNA repeat contains different type II restriction sites (BbsI or SapI) that allow seamless fusion of 19 bp gene-speciﬁc sequences to the vector. Asterisks indicate unique sites. The Eukaryotic Promoter Database is an annotated non-redundant collection of eukaryotic POL II promoters, for which the transcription start site has been determined experimentally. Access to promoter sequences is provided by pointers to positions in nucleotide sequence entries.
