TypeTargeted MutationCartagena
SpeciesMus musculus
Strain nameB6;129P2-Arx<tm1Kki>/6Rbrc
Former Common nameArx-6 KO
H-2 Haplotype
ES Cell lineE14TG2a [129P2/OlaHsd]
Background strain
Strain developmentDeveloped by Kunio Kitamura, Mitsubishi Kagaku Institute of Life Sciences. E14 ES cells were used to generate the mutant mice.
Strain descriptionArx gene knockout mice. A lacZ-neo cassette was inserted into the exon 2 of Arx gene. Hemizygous (-/Y) mutant males die within 12 hrs after birth. Main line: Arx-6 KO (RBRC03438).
Colony maintenanceHeterozygote (female) x Wild-type (male)[C57BL/6JJcl]
