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.
Availability: Cryopreserved as heterozygous embryos
Zygosity genotype: Homozygous as live colony
This model expresses cre-recombinase under the control of the endogenous 5’- hydroxytryptamine receptor 3A (5Ht3a) promoter enabling specific expression in 5Ht3a positive serotonergic neurons. This model possesses a targeted insertion of (T2A)-cre immediately before the translational stop in the open reading frame of the 5Ht3a gene. The 5Ht3a-Cre rat is useful for applications requiring tissue specific expression, including optogenetics and breeding with transgenic floxed lines.
