Do not add LiCl after SolnIII -- that not how's it's done.
After you ppt the plasmid (EtOH or 2-propanol) resuspend it in TE and then
add LiCl to a final conc. of 2 to 2.5M. Let it stand at 0 C for 5h or at
-20 C for 2h. Spin 20min at 15kxg. Discard the RNA pellet and proceed to
re-ppt with alcohol.
