Generation DefinitionsDonating Investigator Radek Skoda, University Hospital Basel Description
These transgenic mice express a codon-improved Cre recombinase (iCre) under the control of the mouse Pf4 (platelet factor 4), or Cxcl4, promoter. Cre recombinase expression is detected in the majority of megakaryocytes. Mice homozygous for the transgenic insert are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. The BAC clone used to generate this strain also contains 4 other genes: Cxcl5, Cxcl7, Cxcl15 and Cxcl3. The additional copy of these chemokine genes in the BAC has no effect on blood count of the mutant mice. This strain represents an effective tool for generating megakaryocyte lineage-restricted specific-targeted mutants.Development
A 100kb BAC containing the mouse Pf4 (platelet factor 4), or Cxcl4, gene with exon 1 replaced by a construct containing the mouse Pf4 (platelet factor 4), or Cxcl4, promoter, a codon-improved Cre recombinase (iCre) sequence, bovine growth hormone polyadenylation signal, nuclear localization signal and a myc tag was injected into fertilized C57BL/6 fertilized oocytes. Founder line Q3 was established, carrying 1 copy of the transgene. Founder animals were maintained as hemizygotes on the C57BL/6 background.A 32 SNP (single nucleotide polymorphism) panel analysis, with 27 markers covering all 19 chromosomes and the X chromosome, as well as 5 markers that distinguish between the C57BL/6J and C57BL/6N substrains, was performed on the rederived living colony at The Jackson Laboratory Repository. While the 27 markers throughout the genome suggested a C57BL/6 genetic background, 2 of 5 markers that determine C57BL/6J from C57BL/6N were found to be segregating. These data suggest the mice sent to The Jackson Laboratory Repository were on a C57BL/6N genetic background.

| Allele Name | transgene insertion Q3, Radek C Skoda | ||
| Allele Type | Transgenic (Cre/Flp) | ||
| Common Name(s) | Pf4-Cre; Tg(Cxcl4-cre)Q3Rsko; | ||
| Mutation Made By | Radek Skoda, University Hospital Basel | ||
| Strain of Origin | C57BL/6 | ||
| Site of Expression | Cre is detected in the majority of megakaryocytes. | ||
| Expressed Gene | cre, cre recombinase, bacteriophage P1 | ||
| Cre recombinase is an enzyme derived from the bacteriophage P1 that specifically recognizes loxP sites. Cre has been shown to effectively mediate the excision of DNA located between loxP sites. After the excision event, the DNA ends recombine leaving a single loxP site in place of the intervening sequence. | |||
| Promoter | Pf4, platelet factor 4, mouse, laboratory | ||
| Driver Note | Pf4 | ||
| Molecular Note | A transgene was created from a BAC where cre-recombinase is driven by the Cxcl4 (Platelet factor 4) promoter. This transgene also contains the Cxcl3, Cxcl5, Ppbp, and Cxcl15 genes. This line has one copy of the transgene inserted with expression restricted to megakaryocytes and platelets, as demonstrated by RT-PCR and Western blotting. [MGI Ref ID J:127229] | ||

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.Ordering Information
