Membrane lipid composition modulates the binding specificity of a monoclonal antibody against liposomes.
    Biochimica et biophysica acta, 1982, Jul-28, Volume: 689, Issue:2

    A hybridoma secreting a monoclonal IgM 'anti-liposome' antibody was produced after injecting a mouse with liposomes containing dipalmitoylphosphatidylcholine, cholesterol, dicetyl phosphate, and lipid A. The antibody was selected by assaying for complement-dependent damage to liposomes lacking lipid A. The monoclonal antibody reacted best with liposomes containing the original immunizing mixture of lipids. Deletion of individual lipid constituents from liposomes diminished the ability of the liposomes to bind (adsorb) the antibody. Binding of the antibody was enhanced by including lipid A or galactosylceramide in the lipid bilayer, or by substituting egg phosphatidylcholine for dimyristoyl- (or dipalmitoyl-) phosphatidylcholine. Sphingomyelin could be substituted for dimyristoylphosphatidylcholine without altering the adsorption of antibody. Although the monoclonal anti-liposome antibody was completely inhibited by phosphocholine, it was probably not a conventional anti-phosphocholine antibody. The antibody apparently had a partial specificity for phosphate, and was inhibited by glycerophosphocholine, glycerophosphate, sodium phosphate, sodium sulfate, and inositol hexaphosphate, but not by choline or inositol.
