Colocalization of EGFP-F and β-galactosidase in TLG 498⁺ R26R⁺ Cre 3487⁺ mice.

<p>Two month old TLG 498⁺ R26R⁺ Cre 3487⁺ transgenic mice were analyzed for colocalization of β-galactosidase in EGFP-F⁺ cells of the visual cortex. A total of 8 sections of 100 µm thickness were used from 3 mice and 201 cells were counted. Numbers between brackets are absolute numbers of cells counted. Between 80–90% of neurons expressing β-galactosidase also express EGFP-F and vice versa.
