Hi,
In the past i have used Fura 2AM dye in neuronal cell lines
The thing is dye uptake can be an issue and if your are planning to setup the chamber where you culture the cells right on the stage then it shud help u circumvent certain problems like cells rounding up ETC
I used 2uM concentration of dye .. Its not toxic Incubate the cells with dye for about 2 hrs before imaging
I think it shud work fine let me know if u need some specific help. Regards,
Johnson.
