New glycoprotein receptor on surface of cancer cells, useful for treatment and diagnosis of cancer and for drug screening, also new specific antibody

摘要

Glycoprotein receptor (I), present on the surface membrane of strongly proliferating cells, especially stomach carcinoma, having at least one determinant that corresponds with a determinant of CFR-1 protein, and binding specifically to human antibody 103/51 and/or the murine antibody 58/47-69 (immunoglobulin M), is new. Independent claims are also included for: (1) method for isolating (I); (2) murine antibody 58/47-69; and (3) preparing an antitumor agent using antibodies specific for (I).
