Subtypes of non-transformed human mammary epithelial cells cultured in vitro: histo-blood group antigen H type 2 defines basal cell-derived cells.
1993
Normal (non-transformed) human mammary epithelial cell lines derived from reduction mammoplasties were analyzed by immunocytochemistry with more than 80 monoclonal antibodies (mAbs) and other specific reagents to tissue-specific and developmentally regulated antigens at different passage levels. A subpopulation of poorly differentiated, proliferating epithelial cells, corresponding to the 'selected' cell type of late passages, is shown to be characterized by a new marker, the histo-blood group antigen H type 2, probably carried on a membrane-bound glycolipid. These cells also express a number of other onco-developmental carbohydrate antigens [Le(y), Le(x), sialosyl-Le(a), precursor of Thoms…

Synthesis of a MUC1-glycopeptide-BSA conjugate vaccine bearing the 3'-deoxy-3'-fluoro-Thomsen-Friedenreich antigen.
2011
A novel MUC1-glycopeptide–BSA conjugate vaccine with a specifically fluorinated Thomsen–Friedenreich antigen side chain at Thr6 was prepared. Preliminary immunological experiments reveal specific binding of the tumor-associated glycopeptide antigen analog by anti-MUC1-mouse antibodies.
The role of the Thomsen-Friedenreich antigen as a tumor-associated molecule.
1990
The Thomsen-Friedenreich antigen (Gal-GalNAc) represents a tumor-associated molecule, which is assumed to be one of the few chemically well-defined antigens with a proven association with malignancy. In order to analyze the role of the carbohydrate structure Gal-GalNAc for gastrointestinal tumors, we immunized Balb/c mice with MCF-7 breast tumor cells together with synthetic Gal-GalNAc linked to a BSA carrier. One monoclonal antibody (82-A6) was established which recognizes the Thomsen-Friedenreich antigen according to the biochemical and serological analysis presented here. In contrast to the studies performed in the past, immunohistochemical results using this antibody 82-A6 did not exhib…
