| − | The tTA atlas III (Nop) is an interactive resource providing access to brain-wide histological images documenting the activity of the Nop-tTA promoter in bigenic mice in which the Nop-tTA promoter regulates the expression of the LacZ reporter gene, encoding the histologically detectible marker β-galactosidase. Detailed knowledge about where in the brain gene expression is regulated is essential for the use and interpretation of such models.

| |
| − | The atlas is based on data from adult 4-6 month old bigenic Nop-tTA/tetO-lacZ-nls-GFP mice and adult 4-6 month old single transgenic tetO-lacZ-nls-GFP mice (controls). Sagittal sections from right hemisphere were cryosectioned at 40 µm. β-galactosidase was labeled blue using X-gal (5-bromo-4-chloro-3-indolyl-β-D-galactoside) as a substrate. Weak counterstaining with Neutral Nuclear Fast Red facilitated detection of boundaries and landmarks without compromising the observation of X-gal labeling. Digital images were created using a slidescanner (AxioScan Z1, Carl Zeiss Microimaging, Jena, Germany).
