The original post related to cloning into M13 and maintaining the ds plasmid,
if I got the jist of it.  M13 doesn't have a eukaryotic origin of replication,
and so won't be able to replicate in mammalian cells - either as double or
single stranded ... will it??  I believe there are vectors available which
allow maintenance in both eukaryotes and prokaryotes, maybe one of these would
have an f1 ori (to allow production of the ss DNA).  If not, maybe you could
add it ... or add a mammailian ori to M13?
