Strain Data Sheet



BRC No.RBRC04549
TypeTargeted MutationCartagena
SpeciesMus musculus
Strain nameB6.129S2-Nmu<tm1Mko>
Former Common nameNMU-KO
H-2 Haplotype
ES Cell lineD3 [129S2/SvPas]
Background strainC57BL/6JJcl
Strain developmentDeveloped by Masayasu Kojima, Institute of Life Science, Kurume University in 2000. D3 ES cells were used to generate the mutant mice. The mice were backcrossed to C57BL/6.
Strain descriptionNmu (Neuromedin U) gene knock-out mice. Exon 9 of the Nmu gene was replaced with a PGK-neo cassette. Homozygous mutant mice show a increased body weight. Nms gene knockout mice (RBRC04550), Nmu and Nms double knockout mice (RBRC04737).
Colony maintenanceHeterozygote × wild-type [or Crossing to C57BL/6JJcl]
