Available Strain Details

Strain Information
Common Strain Name: Rb1 null Pricing and Ordering Information
Strain Nomenclature: B6.129S2(Cg)-Rb1tm1Tyj/Nci
Animal State: Cryoarchived Strains
Release Category (Required for MTA form): B3,D

Strain Description: Mice homozygous for the Rb1tm1Tyj targeted mutation die in utero, apparently from a failure to efficiently produce erythrocytes in the liver. Heterozygous mice develop intermediate lobe pituitary tumors beginning at 8 months of age; C cell tumors of the thyroid are also common in this strain. Retinal tumors, which develop in RB(+/-) humans, have not been observed in this strain.
