Strain Information

BRC No.RBRC06343
TypeTargeted MutationCartagena
SpeciesMus musculus
Strain nameC57BL/6-App<tm2(NL-F)Tcs>
Former Common nameAPP<NL-F>, B6-App/NL-F KI
H-2 Haplotype
ES Cell lineiTL IC1 [C57BL/6NTac]
Background strain
Strain developmentDeveloped by Takashi Saito and Takaomi C. Saido, RIKEN Brain Science Institute in 2009. C57BL/6 derived ES cells were used to generate the mutant mice. A floxed neo cassette was removed by crossing with EIIa-cre mice (B6.FVB-Tg(EIIa-cre)C5379Lmgd/J). C57BL/6 background.
Strain descriptionApp knock-in mice having Swedish mutation (NL) (RBRC06342), Swedish/Iberian (NL-F) mutations (RBRC06343) and Swedish/Iberian/Arctic mutations (NL-G-F) (RBRC06344). Homozygous mutant mice are viable and fertile.
Colony maintenanceHomozygote ×Homozygote [or Crossing to C57BL/6J(Crl)]
