Available Strain Details

Strain Information
Common Strain Name: EGFR-L858R Pricing and Ordering Information
Strain Nomenclature: B6;CBA-Tg(tetO-EGFR*L858R)56Hev/Nci
Animal State: Cryoarchived Strains
Release Category (Required for MTA form): B1


Strain Description: These mice need to be crossed to an appropriate rtTA strain for inducible expression of the EGFR L858R allele. EGFR L858R has been found in lung tumors from patients who respond to the tyrosine kinase inhibitors erlotinib and gefitinib. In double transgenic mice, expression of this mutant in the lung gave rise to lung tumors that required continued EGFR Del L747-S752 expression for survival and regressed when treated with erlotinib (Politi et al., 2006).
