Targeted (Null/Knockout) | Krt12 | keratin 12 |
In this strain, a neo cassette replaces exons 3-7 and intron 7 of the keratin 12 (Krt12) gene with a neomycin resistance (neo) cassette, abolishing gene expression. Keratin 12 is a type I intermediate filament chain keratin, expressed in corneal epithelia. Keratin 12 also pairs with Keratin 3 and forms intermediate filaments in the cornea. Heterozygous mice appear phenotypically normal. Homozygotes are viable and fertile. The cornea of these Ktr12-/- mice are fragile, and contain fewer cellular layers and fewer intermediate filaments.
A targeting vector was designed to replace exons 3-7 and intron 7 of the keratin 12 (Krt12) gene with a neomycin resistance (neo) cassette. The construct was electroporated into 129P2/OlaHsd-derived E14.1 embryonic stem (ES) cells. Correctly targeted ES cells were injected into C57BL/6 blastocysts and the resulting chimeric mice were bred to Black Swiss mice. These mice were backcrossed 20 generations to C57BL/6J mice. Upon arrival at The Jackson Laboratory, mice were bred to C57BL/6J (Stock No. 000664) for at least one generation to establish the colony.

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
