Abstract

The T antigenic determinant was synthesized in the form 8-methoxycarbonyloctyl 2-acetamido-2-deoxy-3-O-(beta-D-galactopyranosyl)-alpha-D-galactopyranoside (6) (beta-D-Gal-(1 goes to 3)-alpha-D-GalNAcO(CH2)8CO2Me). This T-hapten was used to prepare a T-BSA artificial antigen (7) and an immunoadsorbent (8), which were shown to possess the expected immunological properties. Nuclear Overhauser enhancements of the signals for anti-periplanar H-2' and the syn-axial H-3' of the beta-D-galactopyranosyl group were observed on saturation of H-1'. The signal for H-3 of the 2-acetamido-2-deoxy-alpha-D-galactopyranoside residue was also enhanced.
