Strain Information

Former Names STOCK Tg(PFKL)224Yg/J    (Changed: 15-DEC-04 ) Type Mutant Stock; Transgenic; Additional information on Genetically Engineered Mutant Mice. Species laboratory mouse

Development
The transgenic construct for Tg(Pfkl)224Yg has 2.9 kb of the 5' genomic region, the first exon, first intron, and some of the second intron of Pfkl followed by the cDNA sequence extending to the 3' untranslated sequence and then genomic sequence from the 3' untranslated region was place downstream of this. A 22 base pair deletion was introduced into this 3' untranslated sequence in order to provide a system for detection of transgene-derived transcript. This construct was microinjected into fertilized eggs from a CByB6F1 female crossed with a B6D2F1 male and these were implanted into CD1 mothers. Line 224 was found to have several dozen copies of the transgene. In 1994 homozygous males and females from line 244 were sent from Dr. Yorum Groner at The Weizmann Institute in Rehovot, Israel to The Jackson Laboratory. This strain was then maintained at The Jackson Laboratory by sibling breeding homozygotes and in 1995 homozygous embryos were cryopreserved.

Supply Details

Standard Supply

Repository-Cryopreserved. Must Be Recovered. Please refer to pricing and supply notes for further information.

Supply Notes

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.

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.
