title: [N-tris-(beta-D-galactopyranosyloxymethyl)glycine methylamide as an antigenic determinant of neoglycoproteins].
abstract: A chemical synthesis of N-tris (beta-D-galactopyranosyloxymethyl) glycine methylamide (trisgalactosylglycine) has been carried out. Trisgalactosylglicine derivatives of bovine serum albumin, ovalbumin and amyloglucosidase from Aspergillus have been obtained. The binding of trisgalactosylglycine residues to bovine serum albumin and ovalbumin was performed by the carbodiimide method; amyloglucosidase galactosylation was performed by using the reductive amination method. The latter technique seems to be the most mild one because it does not interfere with the peptide structure of the protein being analyzed. The antiserum specifically raised against the trisgalactosylglycine derivative of bovine serum albumin as well as the monospecific antibodies isolated from it can interact with both the antigen and the trisgalactosylglycine derivatives of ovalbumin and amyloglucosidase. Native proteins are not precipitated with this antiserum. This suggests that the trigalactosylglycine residues (bovine serum albumin, ovalbumin, amyloglucosidase) covalently bound to various proteins act as immunologic determinants regardless of the mode of their binding.
