Strain Data Sheet


Strain Information

BRC No.RBRC01105
TypeTargeted MutationCartagena
SpeciesMus musculus
Strain nameB6.Cg-Sema3a<tm1.3Tyag>/TyagRbrc
Former Common namesemaphorin III/D (lacZ) Targeting mice
H-2 Haplotype
ES Cell lineTT2 [(C57BL/6NCrlj x CBA/JNCrlj)F1]
Background strainC57BL/6NCrlCrlj
Appearanceblack [a/a B/B C/C]
Strain developmentDeveloped by Masahiko Taniguchi and Takeshi Yagi, National Institute for Physiological Sciences in 1997. TT2 ES cells were used. The mutant mice were backcrossed to C57BL/6 over 5 times.
Strain descriptionSemaphorin III/D (Sema3a) knockout mice (lacZ reporter). Most of homozygous mice in C57BL/6 genetic background are lethal. About one-tenth of the homozygous mutant mice of ICR background survived (Depositor, personal communication).
Colony maintenanceHeterozygote x Wild-type [or Crossing to C57BL/6NCrlCrlj]
ReferencesNeuron, 19, 519-530 (1997). 9331345
