Strain nameB6;129-Xist<tm4Sado>
Former Common nameXist<IVS19>; B6.Cg-Xist<tm4Sado>
H-2 Haplotype
ES Cell lineR1 [(129X1/SvJ x 129S1/Sv)F1-Kitl<+>]
Background strain
Strain developmentDeveloped by Takashi Sado, National Institute of Genetics in 2006. R1 ES cells were used to generate the mutant mice. A loxP flanked neo cassette was removed by crossing with cre mice (B6).
Strain descriptionXist<IVS19> mice. A second intron of the human gamma-globin gene was inserted into exon 1 of Xist gene. Heterozygous mutant females with paternal mutant allele were embryonic lethality by non-random and abnormal X-inactivation. Tsix knockout (Xist<1loxGFP>)(RBRC01949), Tsix splising (Tsix<SA>)(RBRC01949), Xist/Tsix double knockout (X<dc>)(RBRC01950), Tsix<pA> (RBRC02653), Xist<IVS> (RBRC02654), Xist<delta> (RBRC02655).
Colony maintenanceHeterozygote (female) x Wild-type (male) [C57BL/6JJcl]
