Available Strain Details

Strain Information
Common Strain Name: p53 LSL R172H Pricing and Ordering Information
Strain Nomenclature: 129S4-Trp53tm2Tyj/Nci
Animal State: Cryoarchived Strains
Release Category (Required for MTA form): B3,D


Strain Description: These mice contain a point-mutant allele of Trp53 that can be activated by Cre-mediated recombination. The conditional allele, containing LoxP sites and a transcriptional/translational STOP sequence, is functionally equivalent to a null mutation.

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 heterozygotes. Homozygotes are viable and fertile but have decreased fertility and die young. Easiest to maintain as heterozygotes.
Genotyping Information: Protocol 1: Allele: Trp53<tm2Tyj>
Donating Investigator: Dr. Tyler Jacks
