Tph2-Cre knockin rats

Typically heterozygous rats are cryo-recovered in 10-12 weeks to an age of 7 weeks old. Subsequently homozygous rats to an age of 7 weeks old can be produced within 20-22 weeks.

• Background strain: Long Evans Hooded
• Cre recombinase driven by endogenous Tph2 promoter
• Targeted insertion eliminates possible gene disruption that may occur in random insertion technologies such as BAC

Availability: Cryopreserved as heterozygous embryos
Zygosity genotype: Homozygous as live colony

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.

Origin:

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.
