Does anyone have any experience using Cs-gluconate, Cs-methanesulfonate, Cs-acetate etc. for 
replacing chloride in pipette solutions for whole-cell recording or know of a paper that discusses 
these in detail. I would like info on the advantages and disadvantages of each and the best ways 
to make up the solutions.

Some recently mentioned that Cs-methanesulfonate does not dissociate well in solution thus not 
making Cs available for blocking potassium currents. Have others found this?

Thanks in advance for any advice on this topic
