Available Strain Details

Strain Information
Common Strain Name: Brca2 floxed Pricing and Ordering Information
Strain Nomenclature: STOCK Brca2tm1Brn/Nci
Animal State: Cryoarchived Strains
Release Category (Required for MTA form): C2,D


Strain Description: This strain carries a conditional mutation in the endogenous Brca2 gene. LoxP sites were inserted into introns surrounding exon 11 in the Brca2 locus. Mice carrying the floxed allele have normal development and life span. Removal of the region flanked by the LoxP sites results in mice with the same phenotype as as mice with a conventional Brca2-null mutation - heterozygotes are normal and homozygotes fail to develop.
