Available Strain Details

Strain Information
Common Strain Name: Mlh1 null Pricing and Ordering Information
Strain Nomenclature: B6.129-Mlh1tm1Rak/Nci
Animal State: Cryoarchived Strains
Release Category (Required for MTA form): B


Strain Description: This strain carries a null mutation in the DNA mismatch repair gene Mlh1. Cells from mice homozygous for this mutation are incapable of repairing single-nucleotide and insertion/deletion mismatches. Homozygous males have no detectable mature sperm and are sterile. Homozygous female mice have normal estrous cycles but are also sterile. Both males and females exhibit normal mating behavior. Heterozygous and homozygous mice show cancer susceptibility.

Additional Information
Cryopreservation Mating Scheme: The cryopreservation mating scheme is C57BL/6 females x heterozygous males. When maintained as a live colony, breeder pairs were distributed as a heterozygote (male or female) x wildtype C57BL/6 (male or female). Mutants are generated by mating heterozygous pairs.
