Available Strain Details

Strain Information
Common Strain Name: Mdm2/p53MdmX triple KO Pricing and Ordering Information
Strain Nomenclature: B6;129S-Mdm4GT(VICTR20)7Lex Mdm2tm1BayTrp53tm1Brd/Nci
Animal State: Cryoarchived Strains
Release Category (Required for MTA form): B3,C1


Strain Description: Absence of Mdm2 and/or MdmX induces embryonic lethality that can be rescued fully by co-deletion of p53. These mice present tumor at the same rate and incidence as p53-null mice, and are useful in dissecting p53-independent roles for Mdm proteins in development and homeostasis.

Additional Information
Cryopreservation Mating Scheme: NOTE: AT THIS TIME, ONLY CRYOPRESERVED SPERM IS AVAILABLE. WHEN THE EMBRYO CRYOPRESERVATION EFFORT IS COMPLETE, THE WEBSITE WILL BE UPDATED TO OFFER CRYOPRESERVED EMBRYOS FOR DISTRIBUTION. Cryopreservation mating scheme is homozygous females x homozygous males. When matintained as a live colony average litter size is 4-5. Mice will present with tumors at 7 months.
