Available Strain Details

Strain Information
Common Strain Name: Tyr-HRAS Pricing and Ordering Information
Strain Nomenclature: FVB/N-Tg(Tyr-HRAS)60Lc/Nci
Animal State: Cryoarchived Strains
Release Category (Required for MTA form): B1,D


Strain Description: This strain carries an activated human HRAS gene (G12V) that is expressed in melanocytes. The transgene integrated on the mouse Y chromosome and therefore, only males develop tumors. On an Ink4a/Arf null background, spontaneous cutaneous tumors develop most commonly in the pinna of the ear, torso, tail, and perineum area. Ocular tumors are seen occasionally. Tumors are locally invasive with no evidence of metastasis. On a wild-type Ink4a/Arf background, there is a very low tumor frequency after a long latency.
