We have incorporated antibodies against fibronectin or laminin into liposomes and studied their interaction with insoluble forms of these antigens. The antibodies, after modification by palmitoylchloride, were incorporated into the lipid bilayer by the cholate dialysis method. The antibodies in the

β¦ Synopsis
Polyclonal and monoclonal antibodies to liposomes having various phospholipid compositions have been produced. Binding of the anti-lipid bilayer antibodies is influenced both by the chemical composition and the physical state of the liposomal lipids. The antibodies to liposomes have a 'subsite' in the binding site that recognizes small soluble phosphorylated haptens such as nucleotides (e.g., ATP). The capacity of anti-liposome ant~odies to bind to phosphate is also shared by ant~odies to numerous other substances, including lipid A from Gram-negative bacterial lipopolysaccharide, cardiolipin, DNA, polynucleotides, and lipoteichoic acids from Gram-positive bacteria, Because of similarities of chemical structures between all of these molecules widespread immunological cross-reactivities are observed.
