Available Strain Details

Strain Information
Common Strain Name: Lkb1 flox Pricing and Ordering Information
Strain Nomenclature: FVB;129S6-Stk11tm1Rdp/Nci
Animal State: Frozen Embryo
Release Category (Required for MTA form): B1

Strain Description: These mice carry a functional, conditional allele of Lkb1 (official gene symbol: Stk11) with LoxP sites flanking exons 3 and 6 (Stk11). These animals are phenotypically normal in absence of Cre recombination. Cre-mediated deletion of exons 3-6 lead to embryonic lethality in the homozygous state, whereas heterozygous mice developed gastrointestinal polyps (mucosal hamartomas) with histological features similar to those seen in Peutz-Jeghers syndrome (PJS) patients.
