Dear Mrs. Dvorak,

I´m concerning to this comment:

Cs-gluconate; Cs-methanesulfonate

.....Here's our recipe for a Cs-gluconate-based solution for whole-cell
recording from hippocampal neurons in slice.

For 100 mL of solution:
					final concentration

3.923 g	gluconic acid (Aldrich G195-1)	100 mM
	CsOH 50% in H20 (Aldrich 23,204-1)
7.6 mg	EGTA (Sigma E4378)		0.2 mM
101.65 mg MgCl (Sigma M-8266)		5 mM
953.2 mg HEPES (Sigma H-3375)		40 mM
101.4 mg Mg-ATP	(Sigma A-9187)		2 mM
15.6 mg Li-GTP	(Sigma G-5884)		0.3 mM
34.3 mg QX-314 (optional)		1 mM

.....I haven't done much whole-cell recording myself, so I can't
vouch for the effectiveness of this solution, but it works
fine in other people's hands in our lab.

Can you give me information about the company and the order number  
from QX-314?

This will be great.
