Strain Information

Tlr2
Name: toll-like receptor 2
Synonyms: Ly105
Type: Gene
Species: Mouse
Chromosome: 3
NCBI: 24088
Homologene: 20695
Genetic Alterations

This strain has LoxP sites flanking the third exon of the Tlr2 gen

ES Cell Line
Not applicable
Phenotype

When crossed with a Cre strain, the third exon of the Tlr2 gene will be deleted in cells expressing the Cre recombinase, preventing expression of the Tlr2 protein.
This strain is useful in performing cell-specific deletion of the gene encoding the Toll-like receptor 2 (TLR2) protein. TLR2 is a pathogen recognition receptor that in particular recognizes the pathogen-associated molecular pattern (PAMP) lipoteichoic acid expressed at the surface of Gram-positive bacteria.

Strain GQC Summary
Gene Specific Genotyping:

To request gene-specific and other genotyping services for a strain, please contact the distribution MMRRC Center for more information.

Background Genetic Quality:

The MMRRC has developed a Genetic Quality Control pipeline using the MiniMUGA array to provide additional information to identify and validate genetic backgrounds of MMRRC strains. For more information on whether genetic background data is available, please contact MMRRC_GeneticQC@med.unc.edu. Note: that MiniMUGA genetic background data is not available on all strains, but can be ordered if desired.

Strain Development
CRISPR guide RNAs (gRNAs) were generated by in vitro transcription (IVT) of linearized targeting constructs using the MEGAshortscript T7 Transcription Kit, while Cas9 mRNA was produced from linearized pT3TS-nCas9n with the mMESSAGE mMACHINE T3 Transcription Kit. Both were purified using the MEGAclear Transcription Clean-Up Kit and eluted in RNase-free water. C57BL/6NCr embryos were microinjected with Cas9 mRNA, gRNAs, and two PAGE-purified ssDNA oligos containing LoxP sequences with 75-base homology arms, then transferred to recipient females. Progeny were screened by PCR and Sanger sequencing, and a founder was bred with C57BL/6NTac mice to propagate the strain.


Disclaimer: If MMRRC Strain Genetic Quality Control (GQC; based on MiniMUGA genotyping and analysis) has been completed for this strain, the information might differ from the genetic background information provided by the submitter. MiniMUGA genetic analysis is done on a strain’s tissue samples taken when archived by or ordered from the assigned MMRRC Center.

Order Information

Limited quantities of breeder mice (recovered litter) are available from a cryoarchive; recovered litter usually available to ship in 3 to 4 months.

Cryopreserved material may be available upon request, please inquire to mmrrc@missouri.edu for more information.

Distribution of this strain requires submission of the MMRRC Conditions of Use (COU). A link to the COU web form will be provided via email after an order has been placed; the form should be completed then or the email forwarded to your institutional official for completion.

Additional charges may apply for any special requests. Shipping costs are in addition to the basic distribution/resuscitation fees. Information on shipping costs and any additional charges will be provided by the supplying MMRRC facility.

Some MMRRC strains were submitted by the donor as cryopreserved germplasm, and because these strains were not cryopreserved by the MMRRC, we have not assessed the quality, nor genotype, of this material. Our expertise in reviving mice from various qualities of frozen sperm and embryos, using methods like IVF and ICSI, gives us confidence in successful recoveries in most cases. However, due to the uncertain quality of these samples, we'll limit revival attempts to two per order. Additional attempts are available for a fee, on top of standard charges, if requested. It's important to note that some strains may lack the expected mutation, so we can't assure successful order fulfillment until we attempt to revive the strain.

1 The distribution fee covers the expense of rederiving mice from a live mouse; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.

2 An aliquot contains a sufficient number of embryos (in one or more vials or straws and based on the transfer success rate of the MMRRC facility) to transfer into one to three recipients. The MMRRC makes no guarantee concerning embryo transfer success experienced in the recipient investigator's laboratory. Neither gender nor genotype ratios are guaranteed.

3 An aliquot is one straw or vial with sufficient sperm to recover at least one litter of mice, as per provided protocols, when performed at the MMRRC facility. The MMRRC makes no guarantee concerning the success of these procedures when performed outside the MMRRC facilities.

4 The distribution fee covers the expense of resuscitating mice from the cryo-archive; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.
