Egg yolks from hens immunized with peptidophosphogalactomannan (pPGalManii ), which contains 10 phosphocholine diester residues and is secreted byPenicillium fellutanum , contain antibodies against 5-O -β-d -galactofuranosyl epitopes. These epitopes were the only significant determinants in pPGalManii . Approximately 60-fold less pPGalManii (1.6 μM galactofuran chains) was required for 50% inhibition than galactofurano-oligosaccharides or pPGalMan containing two galactofuranosyl residues per chain.
