Overview

Also Known As:H11, H11^LSL-Cas9

Removal of this mouse colony is imminent. If live mice are needed for your studies, it is advised that they be ordered immediately. After removal, the mice will be available from a cryorecovery.

H11^LSL-Cas9 CRISPR/Cas9 knock-in mice have Cre recombinase-dependent expression of CRISPR associated protein 9 (cas9) endonuclease directed by a CAG promoter. When used in combination with single guide RNAs and a Cre recombinase source, they allow editing of single or multiple mouse genes in vivo or ex vivo.

Detailed Description

These H11^LSL-Cas9 knock-in mice have a loxP-flanked STOP cassette preventing expression of the downstream sequence (cas9), inserted in the Igs2 locus (Hipp11 or H11; an intergenic region on chromosome 11 [cytoband A1 at ~3cM between the Eif4enif1 and Drg1 loci] reported to support high-level global gene expression in conjunction with the CAG (CAGGS) promoter and a higher rate of mitotic/interchromosomal recombination compared to Gt(ROSA)26Sor). Although under control of a CAG promoter, widespread expression of cas9 is prevented by the STOP cassette. After exposure to Cre recombinase, expression of cas9 is observed. Whereas gene editing via viral delivery of cas9 is burdened by packaging size limits, these H11^LSL-Cas9 mice only require the user to select a Cre recombinase driven by the promoter of their choosing and a specific single guide RNA (sgRNA) for generating single or multiple simultaneous mutations. Mice homozygous for the H11^LSL-Cas9 knock-in allele are viable and fertile.

H11^LSL-Cas9 knock-in mice are also available on a B6;129 genetic background (Stock No. 026816).

Development

The H11^LSL-Cas9 knock-in allele has attL-pCA-LSL-3xFLAG-NLS-hSpCas9-NLS-polyA-attR-attP-FRT5 inserted into the Igs2 locus (Hipp11 or H11; an intergenic region on chromosome 11 [cytoband A1 at ~3cM between the Eif4enif1 and Drg1 loci] reported to support high-level global gene expression in conjunction with the CAG (CAGGS) promoter and a higher rate of mitotic/interchromosomal recombination compared to Gt(ROSA)26Sor). Specific details below.
The pattB-LSL-Cas9 targeting vector was created with a full-length attB site, the CMV enhancer/chicken beta-actin core promoter (CAGGS), a loxP-STOP(3xSV40 polyA)- loxP cassette (LSL), a 3xFLAG sequence, a nuclear localization signal (NLS), a human codon-optimized S. pyogenes cas9 gene (hSpCas9), a second NLS and the SV40 polyA signal. (129X1/SvJ x 129S1/Sv)F1-derived R1 embryonic stem (ES) cells were previously targeted with the H11^attPx3 allele (Igs2^tm3.1Luo or H11P3; a unique sequence from the promoter of the yeast his3 gene followed by three shortened tandem attP sites and one FRT5 site). H11^attPx3 mice were backcrossed onto C57BL/6, and then made homozygous (H11^{attPx3/attPx3}). For site-specific ΦC31 integrase-mediated transgenesis, the pattB-LSL-Cas9 construct and ΦC31 integrase mRNA were microinjected into the pronucleus and cytoplasm of H11^{attPx3/attPx3} zygotes. One founder mouse carried the correctly targeted insertion of pattB-LSL-Cas9 into the first and second attP sites of the H11^attPx3 locus. The resulting H11^LSL-Cas9 knock-in allele is therefore attL-CAGGS-LSL-3xFLAG-NLS-hSpCas9-NLS-polyA-attR-attP-FRT5. The H11^LSL-Cas9LSL-Cas9 colony was bred to 2 other mutant lines with B6;129 backgrounds prior to sending agouti males to The Jackson Laboratory Repository in 2015 as Stock No. 026816. Upon arrival, some mice were then backcrossed to C57BL/6J inbred mice (Stock No. 000664) using a marker assisted protocol - the resulting C57BL/6J-congenic H11^LSL-Cas9 strain is Stock No. 027632.

Payment Terms and Conditions

Terms are granted by individual review and stated on the customer invoice(s) and account statement. These transactions are payable in U.S. currency within the granted terms. Payment for services, products, shipping containers, and shipping costs that are rendered are expected within the payment terms indicated on the invoice or stated by contract. Invoices and account balances in arrears of stated terms may result in The Jackson Laboratory pursuing collection activities including but not limited to outside agencies and court filings.

The Jackson Laboratory's Genotype Promise

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
