We always had to wash the infected E. coli cell pellet MANY times to
minimize the amount of ssM13 in our dsM13 preps, remember the dsM13 is
just an intermediate in the rolling circle replication of the phage and as
such is present in a much smaller amount. I belive we still always had
some ssM13 present. I guess hydroxy appetite could give you what you want,
its easier than CsCl good luck
