Strain Information

BRC No.RBRC11137
TypeTargeted MutationCartagena
SpeciesMus musculus
Strain nameB6J.B6N-Qrfp<tm2.1(icre)Stak>
Former Common nameQrfp-iCre
H-2 Haplotype
ES Cell lineRENKA [C57BL/6NCrlCrlj]
Background strain
Strain developmentDeposited by Takeshi Sakurai, University of Tsukuba, 2020. Mice were generated using RENKA ES cells derived from C57BL/6NCrlCrlj. Mice were further backcrossed to C57BL/6J for 10 generations. Pgk-neo fragment was deleted from this strain.
Strain descriptioniCre knock in mice at the translation initiation codon of the Qrfp gene.
