FVB/N-Tg(Zp3-cre)3Mrt/J

Stock number: 003377
Product name: Zp3-cre
Research areas: Research Tools

Description

These Zp3-cre mice express a transgene containing cre with the mouse zona pellucida 3 (Zp3) promoter.

Detailed description

The strain originated on an FVB/N background and is currently on the same background. The investigator maintains the strain by breeding hemizygotes. Homozygotes are subfertile. This is a transgenic line in which cre expression is controlled by the regulatory sequences from the mouse zona pellucida 3 (Zp3) gene, which is normally expressed exclusively in the growing oocyte prior to the completion of the first meiotic division. This strain would be useful for deleting a floxed sequence specifically in the female germ line.

Development

A CreZp3 construct was injected into FVB/N zygotes to produce the founder line. The strain originated on an FVB/N background and is currently on the same background. Female homozygotes are subfertile.
