Available Strain Details

Strain Information
Common Strain Name: p16(Ink4a) null Pricing and Ordering Information
Strain Nomenclature: FVB.129-Cdkn2atm2.1Rdp/Nci
Animal State: Cryoarchived Strains
Release Category (Required for MTA form): C3


Strain Description: The loss of the p16(Ink4a) tumor suppressor gene (sometimes accompanied by the simultaneous loss of p19(Arf)) plays a role in both human and murine tumor development. This strain carries a null allele of the p16(Ink4a) gene while retaining normal p19(Arf) function. Mice carrying this allele exhibit thymic hyperplasia, enhanced T-cell proliferative responses and increased spontaneous and carcinogen-induced (DMBA and urethane) tumors. Spontaneous tumors are mostly sarcomas and lymphomas, the median tumor free survival is ~75 weeks.
