These VEGFR2e3loxP/e3loxP mice may be useful studying angiogenesis and vascular differentiation.

These VEGFR2e3loxP/e3loxP mutant mice possess loxP sites flanking a frt-flanked PGK-neo cassette and exon 3 of the kinase insert domain protein receptor (Kdr) gene. KDR, also known as VEGFR2 (vascular endothelial growth factor receptor 2), is a type III receptor tyrosine kinase which mediates VEGF-induced regulation of angiogenesis, vascular development, vascular permeability, and embryonic haematopoiesis. Homozygous for this allele are viable and fertile. When these mutant mice are bred to mice that express Cre recombinase, resulting offspring will have exon 3 deleted in the cre-expressing tissues.
A targeting vector was designed to insert a loxP site upstream of exon 3, and a frt-flanked PGK-neo cassette followed by a second loxP site just downstream of exon 3 of the kinase insert domain protein receptor (Kdr) gene. The construct was electroporated into 129S1/Sv-Oca2+ Tyr+ Kitl+-derived CJ7 embryonic stem (ES) cells. Correctly targeted ES cells were injected into blastocysts and resulting chimeric males were bred to CD1 females. Mice heterozygous for this conditional VEGFR2e3loxP/e3loxP allele were bred with Flp transgenic mice to delete the neo cassette, and progeny were crossed to remove the Flp-expressing transgene. Upon arrival at The Jackson Laboratory, mice were bred to C57BL/6J (Stock No. 000664) for at least one generation to establish the colony.

We will fulfill your order by providing at least two carriers for each strain ordered. The total number, sex, and genotypes provided will vary, although typically 8 or more animals are provided. Please check genotypes which will be recovered. While the genotypes of all animals produced will be communicated to you prior to scheduling shipment, the genotypes of animals provided may not reflect the mating scheme and genotypes described in the strain description. Animals are typically ready to ship in 11-14 weeks. If a second recovery is required to produce the minimum number of animals, then delivery time would increase to approximately 25 weeks. If we fail to produce animals of the correct genotype, you will not be charged. We cannot guarantee the reproductive success of mice shipped to your facility. If the mice are lost after the first three days (post-arrival) or do not produce progeny at your facility, a new order and fee will be necessary.
Cryorecovery to establish a Dedicated Supply for greater quantities of mice. Mice recovered can be used to establish a dedicated colony to contractually supply you mice according to your requirements. Price by quotation.
