Available Strain Details

Strain Information
Common Strain Name: p53 R172H Pricing and Ordering Information
Strain Nomenclature: 129S4-Trp53tm2.1Tyj/Nci
Animal State: Cryoarchived Strains
Release Category (Required for MTA form): B3,D


Strain Description: These mice express point-mutant p53 under control of the endogenous Trp53 promoter. Heterozygous mice have an increased tumor burden relative to Trp53+/- mice but similar survival curves. The animals show a broad tumor spectrum with an increased frequency of carcinomas, osteosarcomas, hemangiosarcomas, and lymphoblastic lymphomas. Osteosarcomas are more frequently metastatic. An improved model for Li-Fraumeni Syndrome.

Additional Information
Cryopreservation Mating Scheme: The cryopreservation mating scheme is 129S4 females x heterozygous males. When maintained as a live colony, breeder pairs were distributed as heterozgyotes. Homozygotes are fertile and viable but have decreased fertility and short lifespan. Easiest to maintain as heterozygotes.
Genotyping Information: Protocol 1: Allele: Trp53<tm2.1Tyj>
Donating Investigator: Dr. Tyler Jacks
