Availability: Live colony
Zygosity genotype: Homozygous
This model expresses cre-recombinase under the control of the endogenous Tryptophan Hydroxylase 2 (Tph2) promoter enabling specific expression in Tph2 positive serotonergic neurons. This model possesses a targeted insertion of (T2A)-cre immediately before the translational stop in the open reading frame of the Tph2 gene. The Tph2-Cre rat is useful for applications requiring tissue specific expression, including optogenetics and breeding with transgenic floxed lines.
The Tph2-Cre KI rat model was originally created at SAGE Labs, Inc. in St. Louis, MO and distributed out of the Boyertown, PA facility. The line continues to be maintained through the original SAGE Labs animal inventory acquired by Envigo, then Envigo was acquired by Inotiv in 2021.
