Type JAX® GEMM® Strain - Congenic Additional information on JAX® GEMM® Strains. Type JAX® GEMM® Strain - Mutant Strain Type JAX® GEMM® Strain - Targeted Mutation Mating System Homozygote x Hemizygote (Female x Male) Species laboratory mouse Donating Investigator Stuart Orkin, Harvard Medical School Generation N8+F5 (05-DEC-07) Strain Description
Homozygous females and hemizygous males for the targeted mutation are viable, fertile, and normal in size. This mutation results in the complete ablation of the eosinophil lineage, even under conditions that normally stimulate eosinophil development, without affecting the development of other GATA-1 dependent lineages (erythroid, megakaryocytic, and mast cells). Expression of the endogenous gene is observed in erythroid and bone marrow cells. This mutant may be useful for in vivo studies of eosinophil function and eosinophil-related pathologies, including asthma and pulmonary physiology.Strain Development
A targeting vector was designed to replace the double GATA-site 21 bp upstream of the first hematopoietic exon of the X-linked endogenous gene. This vector, containing a loxP-flanked phosphoglycerate kinase promoter driven neomycin resistance gene (PGK-neo), was electroporated into 129S1/Sv derived CJ-7 embryonic stem (ES) cells. Correctly targeted ES cells were then transiently transfected with a cre recombinase vector to remove the PGK-neo resulting in a mutant allele where the double GATA-site is replaced with a single loxP site. These cells were injected into C57BL/6 blastocysts and the resulting chimeric males were backcrossed to C57BL/6 females. Resultant heterozygotes were backcrossed to BALB/c for eight generations before being made homozygous/hemizygous.

| Molecular Note | A high-affinity, palindromic "double" GATA protein binding site in the Gata1 promoter presumed to mediate positive Gata1 autoregulation was replaced by a floxed Pgk-neo cassette; transient Cre recombinase expression in ES cells left a single loxP site flanked by two Not1 sites. The 21-bp deleted segment comprised nucleotides -691 through -671 upstream of the last nucleotide of the first hematopoietically expressed exon of Gata1. [MGI Ref ID J:88711] | ||

| Standard Supply | Repository-Live. A collection of over 1000 strains maintained as live colonies. Individual colonies are sized to meet current customer demand. Delivery for orders of 10 mice or less ranges on average from one to eight weeks; mice are generally shipped between four to six weeks of age with a maximum shipping age of ~nine weeks. Colony sizes do not generally support stringent age specifications for large volumes of mice; however custom orders and larger quantities of mice are easily arranged. Estimated ship dates for all orders provided within 48 hours of order placement. |
