Hi, Thomas
Quiagen plasmid prep is reported to reduce LPS contamination
efficiently.
    see	Ref. Human Gene Therapy 6:317-323(1995)
	     Bacterial LPS copurified with plasmid DNA : Implications for
Animal 		Models and Human Gene Therapy
	     Wicks et al.

DNA Etox reagent from Sterogene Bioseparations, Inc.(sterogene at aol.com)
removes endotoxin from DNA preparations.

Hope it helps.
