Strain Data Sheet



BRC No.RBRC01814
TypeTargeted MutationCartagena
SpeciesMus musculus
Strain nameB6.Cg-Grin2b<tm1Mim>/MimRbrc
Former Common nameGluRε2 KO mouse
H-2 Haplotype
ES Cell lineTT2 [(C57BL/6NCrlj x CBA/JNCrlj)F1]
Background strain
Strain developmentDeveloped by Dr. Masayoshi Mishina at Tokyo University in 1995. A pgk-neo was transfered into TT2 ES cells to replace the exon encoding the transiation initiation site of Grin2b gene. The Mint deficient mice were backcrossed to C57BL/6N for 14 times.
Strain descriptionB6.Cg-Grin2b<tm1Mim>. The Grin2b gene is one of the glutamate recepoter channel subunit families forming NMDA receptor channel, which is important for synaptic plasticity. Homozygous mutant mice show impairments in suckling and die shortly after birth.
Colony maintenanceBackcross to C57BL/6 (Heterozygote x C57BL/6NJcl)
