don't know if BSA will work for small hydrophobic molecules, and if 
you want to mess around with it I'm not sure whether to recommend 
delipidated or not (I can think of armchair rationales for either one

        Our lab is using dimethyl sulphoxide as a carrier solvent for
hydrophobic contaminants (PCBs, dioxins, furans and PAHs) in order to 
administer these contaminants to a rainbow trout liver cell line.  I have 
read that DMSO can result in a more differentiated phenotype as well as 
affect the penetration of the contaminant at the site of action.  If 
anyone knows of any other carrier solvent that may be more "neutral", I 
would appreciate the feedback.
