Availability & Fees Order this Strain
1 When indicated as "assessed by MMRRC" ("YES"), please note that the information presented on this strain is to the best of our knowledge correct and up-to-date at the the MMRRC Distribution Center assigned to maintain and distribute this strain. This information is subject to change due to breeding, maintenance, and other actions. Please direct any questions on the information presented in this table to the MMRRC Distribution Center.
2 If an assessment has not been performed by the MMRRC (as indicated by "NO"), investigators may request specific testing for a fee. Requests should be submitted directly to the MMRRC Distribution Center assigned to the management, archiving, and distribution of the strain. A full listing of available testing and analytical services is available at https://www.mmrrc.org/about/services.php.
3 This information may or may not apply to each individual engineered allele (e.g., Cre, FlpO) present in the strain.
4 Recovery refers to thawing, in vitro fertilization (IVF), and/or embryo culture leading to live offspring.
None/Normal/Wild-type
Conditional phenotype: Deletion of exons 9 and 10 via Cre-mediated recombination in the germline results in reduced body weight.
To request gene-specific and other genotyping services for a strain, please contact the distribution MMRRC Center for more information.
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.
Lin K, Qiang W, Zhu M, Ding Y, Shi Q, Chen X, Zsiros E, Wang K, Yang X, Kurita T, Xu EY. Mammalian Pum1 and Pum2 Control Body Size via Translational Regulation of the Cell Cycle Inhibitor Cdkn1b. Cell Rep. 2019 Feb 26;26(9):2434-2450.e6. doi: 10.1016/j.celrep.2019.01.111. (Medline PMID: 30811992)
The Pum1 sequence obtained from the NCBI mouse genomic database was used to generate a Pum1-targeting construct. The targeting vector, which includes exons 9 and 10 flanked by loxP elements and a FRT flanked Neo cassette, was linearized and electroporated into 129 Sv/J mouse ES cells. After selection with G418, ES cells containing the targeted Pum1 allele were identified by Southern blot. Positive ES cells heterozygous for the allele containing the integrated homologous recombinant were injected into wild-type mouse blastocysts. Resulting chimeric males were mated with C57BL/6 females producing targeted (Pum1ta/wt) mice. Pum1ta/wt mice were crossed with a germline-specific Flp transgenic mouse to remove the Neo cassette and generate mice heterozygous for a floxed Pum1 allele. These mice were bred to homozygosity to generate homozygous Pum1fl/fl mice on a hybrid (C57BL/6J and 129Sv/J) background.
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.
Colony Surveillance Program and Current Health Reports
Limited quantities of breeder mice (up to 2 males and 2 females or 4 mice) per investigator per month are available from a live colony, usually available to ship in under 12 weeks. Larger quantities may be available, please contact the distributing center directly at mmrrc@missouri.edu for more details.
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.
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.
