ABSTRACT Egg yolks from hens immunized with peptidophosphogalactomannan (pPGalManii), which contains 10 phosphocholine diester residues and is secreted by Penicillium 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.
