protein precipitation - protein precipitation (Jan/16/2003 )

I precipitates my protein with acetone, but I'd like to get rid of salts as the gel is not migrating well. What can I use to wash the pellet?

Many thanks,
Alberto

Hi Alberto,

I had the same problem. I tried with a second acetone precipitation and the salt sediment was almost away and the electrophoresis worked very good.
I hope that can help you.

hi
as usual we have two or three acetone precipitation ,if salt of solution is high,it is a good way to use TCA precipitation,
try it

Did you use the gel for western blot? I read a paper using 300ug/lane, I really don't know how to get such high concentration of protein. Hope the percipitation will help!
