Abstract (EN):
A panel of 56 murine monoclonal antibodies submitted to the ISOBM TD-4 (MUC1) Workshop was analysed for reactivity against nonglycosylated and in vitro Ga1NAc glycosylated peptides. Twenty-six antibodies reacted with nonglycosylated MUC1 peptides containing 3-5 tandem repeats, The reactivities of most of the antibodies were not affected by Ga1NAc glycosylation of the peptides, Antibody #147 (decoded as BCP9) reactivity was inhibited when 3 mol of Ga1NAc per repeat were incorporated in the peptide (at sites T in GVTSA and ST in GSTAP), whereas the reactivity with Ga1NAc glycosylated peptides with 2 mol of Ga1NAc per repeat (sites T in GVTSA and T in GSTAP) was unaffected, This is in agreement with the epitope defined as GSTAP.
