Q Yang et al.
Analytical biochemistry, 218(1), 210-221 (1994-04-01)
Interactions between water-soluble substances and immobilized liposomes or proteoliposomes can be analyzed by chromatographic procedures. Methods were therefore developed to sterically immobilize large amounts of liposomes in gel beads. First, freeze-thawing of moist Sephacryl S-1000 beads mixed with egg yolk
