Strain Data Sheet



BRC No.RBRC05918
SpeciesMus musculus
Strain nameB6.Cg-Tg(TOPGAL)
Former Common name
H-2 Haplotype
ES Cell line
Background strainC57BL/6JJcl
Strain developmentDeveloped by Takuya Murata, RIKEN BioResource center in 2012. The mice were backcrossed to C57BL/6 from TOP-GAL mice of ICR background (RBRC02228).
Strain descriptionIns-TOPGAL transgenic mice for visualizing Wnt signal pathway. The transgene contains the nLacZ gene under the control of a TOPFLASH promoter (6x TCF binding motifs upstream of a TK promoter). The transgene construct was flanked by the insulator core elements.
Colony maintenanceCarrier x Noncarrier [C57BL/6JJcl] Tg mice are viable and fertile.
