I believe that the SOLR cell are generally only used (at least in our lab) to 
rescue the phagmid (i.e. pBluescript) during the "in vivo excision" procedure 
of library screening. We routinely retransform our rescued phagmid into 
XL1-Blue MRF' cells (E. coli) due to the poor quality plasmid preps obtained 
with SOLR cells.
