Source sentences:
text: The lipids may be added directly to a low-conductivity aqueous medium or, alternatively, may be added to an aqueous medium containing a zwitterionic compound whose isoelectric point is substantially different from that of the pH of the medium (such that the medium has relatively high conductivity).
text: In a second general embodiment of the method, the lipids are added to an aqueous medium containing a zwitterionic compound, at a pH which is substantially different from the isoelectric point of the compound.
