try an electrophysiology bath solution....cells sit in this for hours...

150mM NaCl
4mM KCl
1mM CaCl2
1mM MgCl2
10mM HEPES (pH 7.2 with NaOH)

this is the external solution they use....i used it once to incubate cells
at room temperature (in presence of luciferin) for an hour or so...they
didnt appear to choke on it ;)
