Strain Information
Common Strain Name: WAPT121 Pricing and Ordering Information
Strain Nomenclature: B6D2F1-Tg(WAPT121)66Tvd/Nci
Animal State: Cryoarchived Strains
Release Category (Required for MTA form): C1,D


Strain Description: WAPT121 transgenic mice express T121, a trucation mutation of SV40 antigen that binds and inactivates all pRB-related proteins, under control of whey acidic protein (WAP) promoter. T121 expression was detected in the mammary gland (Simin et al., 2004). Transgenic females failed to nurse pups because of lactation defects. Multi-pregnant females developed mammary tumors at 11-15 months after the first pregnancy. Tumorigenesis is accelerated 2-fold on a Trp53 heterozygous background.

Additional Information
Cryopreservation Mating Scheme: The cryopreservation mating scheme is B6D2F1 females x heterozygous males. Females do not nurse young so can't be used for breeding. When maintained as a live colony, breeder pairs were distributed as a hemizygote male x wildtype B6D2F1 female. Average litter size is 9.
Genotyping Information: Protocol 1: Allele: Tg(WAPT121)66Tvd
Donating Investigator: Dr. Terry Van Dyke
