Hello fellow netters:
   Does anyone out there have experience with the lac switch
system supplied by stratagene?  We have selected a number of
clonal cell lines expressing both the RSV vector and the
repressor protein, but have only seen a maximum of 2.5 fold
induction to 5 mM IPTG.  Have any of you tried the system and
found clonal cell lines with higher fold inductions?  Our results
could be simply not screening through enough clones.
   Thanks in advance.
