Description
Mice that are homozygous for the targeted mutation are viable, normal in size, and do not display any gross physical or behavioral abnormalities. Endogenous protein expression is unaffected by the loxP sequences flanking an upstream regulatory region (URE). When bred to mice with a cre recombinase gene under the control of a promoter of interest, the URE of the targeted gene is deleted in the tissue of interest. Deletion of this "floxed" URE may be useful in studying T cell lymphoma, AML and other cancers, as well as transcription factors, hematopoiesis, and development of multiple cell lineages.

Genes & Alleles

Gene & Allele Information

Allele Symbol		Sfpi1tm1.2Dgt
Allele Name		targeted mutation 1.2, Daniel G Tenen
Allele Type		Targeted (Floxed/Frt)
Common Name(s)		-14kb UREloxP (neo-); URE floxed (neo-);
Strain of Origin		(129X1/SvJ x 129S1/Sv)F1-Kitl<+>
ES Cell Line Name		R1
ES Cell Line Strain		(129X1/SvJ x 129S1/Sv)F1-Kitl<+>
Gene Symbol and Name		Sfpi1, SFFV proviral integration 1
Chromosome		2
Gene Common Name(s)		Dis-1; OF; PU.1; SPI-1; SPI-A; Sfpi-1; Tcfpu1; Tfpu.1; transcription factor PU.1;
General Note		Crossing mice bearing this "floxed" allele with mice expressing Cre recombinase under control of a selected promoter will result in excision of the URE in the cell/tissue type of interest.
Molecular Note		This allele was generated by crossing mice bearing Sfpi1tm1Dgt with mice ubiquitously expressing FLP recombinase to produce progeny in which the FRT-flanked PGKneo cassette has been deleted. This leaves a single FRT site immediately upstream of the 5' member of a pair of loxP sites flanking the 3.4-kb upstream regulatory element (URE) that is located 14 kb upstream of the endogenous gene. Expression of the protein is unaffected by presence of the FRT or loxP sites. [MGI Ref ID J:106788] [MGI Ref ID J:90331]

Supply Notes

Cryopreserved Embryos This strain is also available as cryopreserved embryos from our Repository. Orders for cryopreserved embryos are supplied subject to a signed agreement that must be returned to the Customer Service Department after order placement. Experienced technicians at The Jackson Laboratory have recovered frozen embryos of this strain successfully. We will provide you enough embryos to perform two embryo transfers. The Jackson Laboratory does not guarantee successful recovery at your facility. For complete information on purchasing embryos from our repository, please visit our Cryopreserved Embryos web page. Cryorecovery - Standard. The recovery process begins when a signed agreement form is returned to the Customer Service Department after order placement. Although results vary by strain, at least two males and two females (two pairs) will be provided, typically within 15 weeks of our receipt of the signed agreement form. If the first recovery attempt is unsuccessful or only one pair is recovered, a second recovery will be done, extending the delivery time to approximately 25 weeks. At least one member of each pair will be of known genotype and will carry the mutation if it is a mutant strain. Please note that pairs may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation of the strain. Mating schemes are sometimes modified for successful cryopreservation. Price represents a repository maintenance fee, which includes the cost of recovery of the strain from the cryopreservation resource and the periodic replacement of the frozen embryos used for recovery. Cryorecovery to establish a Dedicated Supply for greater quantities of mice. One to two pairs will be recovered to establish a Dedicated Supply of mice. Price by quotation. For more information on Dedicated Supply, please contact JAX® Services, Tel: 1-800-422-6423 or 1-207-288-5845. This strain is included in the Induced Mutant Resource Colony collection.

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.
