does anyone know a transgenic mouse model to measure Ca2+ levels in neuronal tissue by confocal microscopy (probably by FRET? any hint will help...

I suppose this is a culture then, and not a mouse on the table.

o.O

hmm, not sure if this will help...

..I don't think Ive seen much on FRETing neural tissues, you might want to check out other models such as alzheimers, maybe it will lead to a clever solution..

I'm not completely sure why you're looking at transgenic models for intracellular calcium measurements. Fura-2 is a standard ionophore for measuring calcium levels in cells in response to chemical stimuli. You might also look at Cameleon, a CamKII-GFP hybrid protein that can be transfected or transduced into cells to visualize calcium concentration.

that is the thing: If you have mutant mice stably expressing those calcium-senstive fluorescent proteins you can measure calcium in living mice...
