M13 Phage purification, How ??

[Hayssam Zakaria]

I am looking for a method to precipitate M13 phages. We are interested in
the phage coat proteins and want to visualize them on SDS-PAGE.
TCA-precipitation seems to result in a lot of degradation. 
How about ultracentrifugation ?? Anybody got a recipe ??

   Thanks
