Product description: The estragen receptor (ERT2) under the Bone marrow x (Bmx) promoter (Bmx-Cre-ERT2) mouse exhibits tissue-specific expression of an inducible Cre-ERT2 fusion protein, enabling tamoxifen-induced Cre recombinase activity in arterial endothelial cells. The Bmx-Cre-ERT2 mouse is an ideal tool in the study of gene function in angiogenesis, atherosclerosis and neovascularisation. Administration of tamoxifen induces nuclear translocation of the Cre-ERT2 fusion protein, and subsequent Cre recombinase activity, allowing knockout/knockin/transgene studies of loxP flanked genes in endothelial cells.Non-induced Bmx-Cre-ERT2 mice demonstrate no Cre recombinase activity, while tamoxifen-induced Bmx-Cre-ERT2 mice demonstrate high penetrance in endothelial cells (95%+), significantly higher than existing endothelial Cre models currently available.
Conditional: Yes
Conditional description: Conditional Cre-ERT2 expression under Bmx promoter enabling tissue-specific recombinase in arterial endothelial cells; inducible Cre activity by treatment with hormone (tamoxifen) enabling inducible translocation of Cre-ERT2 to nucleus.
Genetic background: A Bmx-Cre-ERT2 transgene vector, containing a genomic VECad promoter fragment fused to a Cre-ERT2 cDNA, was injected into fertilised embryos (C57BL/6 or FVB/N). Founder lines were back-crossed to establish mice heterozygous for the Bmx-Cre-ERT2 transgene.

Shipping conditions: Embryo/Spermatoza- Dry Ice
